With interests in science and nature, I explores topics from a unique and sometimes controversial perspective.
Could Megalodon Still Live?
No. The megalodon shark went extinct millions of years ago. At a maximum length of up to 60 feet, it was the largest shark that ever lived, a wrecking machine of teeth and muscle that preyed on adult whales. If there were still a viable population of such creatures out there we would surely know about it.
There has been a lot of controversy surrounding the megalodon shark in recent years. This has, in turn, led to a great deal of confusion about megalodon encounters in modern times, as well as the real creature that swam in our oceans for millions of years.
Unfortunately, some people have interpreted this misinformation to mean megalodon is entirely made up. That is far from the case.
Was Megalodon a Real Shark?
Yes! Megalodon really did exist. One reason we know this is because of fossil teeth and vertebrae left behind. Because shark skeletons consist mostly of cartilage rather than bone, these are the only parts that fossilize.
No living or dead specimen has ever been recovered. There are no "official" sightings on record.
Megladon teeth are much larger than those of any living shark, including the great white, and from them, researchers have been able to determine the size, weight, and even some of the habits of the real megalodon shark.
So, when we talk about megalodon we are looking at it from two different points of view: Paleontology and Cryptozoology. I think it is important to distinguish the difference.
- The shark of paleontology can be studied by looking at the fossil record and living sharks in order to puzzle out what the real megalodon may have been like. From a paleontology perspective, this shark is officially extinct, but that doesn’t make it any less interesting.
- The possibility of a living megalodon is a stance taken by cryptozoologists, and it is not supported by mainstream science. There is no credible evidence that megalodon still exists today.
So, what makes people so sure megalodon is really extinct? In this article, we'll examine the possibility that the megalodon could still be out there.
Giant Teeth and Massive Jaws
We like to think of megalodon as like a giant great white shark. Though they may have looked similar, paleontologists point to slight differences in the megalodon teeth as proof that the megalodon shark is not closely.
The largest megalodon teeth can measure seven inches long — the size of a grown man's hand. Even after countless centuries, some fossilized megalodon teeth are still sharp to the touch.
If meg were still alive today, we would see wounds made by these tremendous teeth the bodies of whales that escaped megalodon encounters with lives, just as we see scars made by great whites on the bodies of living seals.
A Powerful Bite Force
Regardless of its heritage, this shark had a set of chompers never seen in the animal kingdom before or since. Researchers have calculated that this massive shark may have had a bite force of 18 tons!
A Tyrannosaurus Rex had a bite force of only one-third that. The strongest biter in our world today is the saltwater crocodile, and they only come in around 3,700 pounds.
It's clear that the teeth and jaws were made for destruction. Interestingly, some researchers say it may have bitten off the fins of its prey before finishing it off. That makes the megalodon not only powerful but capable of a certain amount of precision as well.
Again, we should see evidence of these powerful jaws in nature today. The megalodon shark would be the absolute apex predator of the modern ocean if it still existed.
Megalodon Behavior and Hunting Technique
Much like the modern great white, megalodon was probably an ambush predator that took its prey by surprise, either from below or by approaching at great speeds. This would have meant it was a very active shark, not some lumbering giant like the whale shark. It was a coastal shark, hunting offshore. Again, like our modern great white.
Megalodon would have been found in just about every ocean of the world, preying on whales, dolphins and other marine mammals, and even giant sea turtles. In short, it would have eaten just about anything it wanted. If it were really around, it would not be hard to spot.
A massive, 60-foot predator hunting whales close to shore would surely be well-known, not to mention widely feared.
Scientists think that the megalodon young lived in shark nurseries like great whites do. These are areas, usually close to shore, where young sharks can grow and feed in relative safety.
Megalodon young may have started out eating fish or other small prey items, and then moved on to larger prey as they got bigger.
So where are the baby sharks?
How Did Megalodon Go Extinct?
There are a few theories. One says that, as the environment entered a cooling period, sea levels began to fall and currents shifted, causing not only a cooling of the ocean itself but also a shift in the food supply. Theoretically, the megalodon shark either couldn’t adapt to the colder climate, the food issues, or both.
There is also evidence that the situation may have been complicated by the evolution of other large, predatory marine creatures that may have infringed on megalodon’s niche. The rise of species such as orca (the killer whale) may have speeded meg's extinction.
Unfortunately, even the strongest creatures are no match for Mother Nature. While Meg inhabited every ocean of the world, the planet was a much warmer place back then.
The Lazarus Taxon and the Megalodon Shark
So what makes some people think they megalodon shark could still be around? More importantly, has anything like this ever happened before?
In fact, there is precedence for marine creatures turning up when the odds are stacked against them. Some of them, like the megalodon shark, were once thought extinct or believed to only be myths.
- Megamouth Shark: The incredible megamouth shark is another sea creature that can grow to enormous size, but it was not discovered until 1976. This beast eluded researchers for so long because it lives in deep water, and comes closer to the surface only at night.
- Giant Squid: The giant squid is a huge creature, reaching up to 30 feet in length, dwelling in the deepest parts of the ocean. Though science eventually knew of its existence from bodies washed ashore and scars left on the bodies of whales, no live adult specimen was ever caught on film until 2004. Now we know much more about these creatures, and that there is an even larger monster squid out there.
- Colossal Squid: The Colossal Squid is an enormous real-life sea monster, with the largest specimens weighing over half a ton. Even though it was discovered in 1925, we still know very little about this beast. Colossal and giant squid sightings by ancient sailors are probably what led to legends of the Kraken sea monster
- Coelacanth: The coelacanth is an even stranger case. This bizarre fish was thought to have gone extinct 65 million years ago, until they were discovered in 1938, live and well, off the coast of South Africa. The coelacanth is a prehistoric fish, referred to as the Living Fossil. While they're not giants like megalodon, the megamouth, or the Giant Squid, they do reach over six feet in length.
A Lazarus Taxon is a species that appears to have gone extinct, but then is found alive again.
Usually, as is the case with the Coelacanth, there is a small remnant population somewhere that had gone unnoticed, at least by modern science. Often, locals know about the animals, but because a biologist hasn't confirmed it the species remains officially extinct.
Does Megalodon Live in the Mariana Trench?
For meg to still be still alive, it would have had to adapt to colder temperatures, a different breeding pattern, and greatly different food sources. It is obviously not hunting offshore near areas populated by humans. So where did it go?
Some speculate that megalodon populations may have survived in the Mariana Trench and other deep parts of the ocean.
Certainly, we know that whales and giant squids venture very deep, so it is conceivable that megalodon would have the food it requires. In fact, recent research on great white sharks shows they may dive fairly deep in search of food.
If meg followed similar habits, perhaps it could have made the adaptations to deep-ocean life much easier than some experts suggest.
Unfortunately, the larger an animal is, and the more specific its niche, the harder a time it has in adapting to environmental changes. It's unlikely that the vast majority of these sharks would have been able to adapt to a major shortage in their food supply. An animal that evolved to feed on large marine mammals would have a tough time switching to oceanic fish, for example.
Historic Megalodon Sightings and Evidence
Just for fun, here are a handful of stories that suggest megalodon is still alive:
- Huge Teeth Found by HMS Challenger: In 1875, two megalodon teeth were dredged up during a deep-sea expedition by the HMS Challenger, dated only 10,000 - 15,000 years old. If the methods used were accurate, this would mean it went extinct much more recently than previously believed, and make it a contemporary of modern humans. Ten thousand years is only a blink of an eye in the world of paleontology. It does not take a great imagination to think the megalodon shark may have survived the past 10,000 years undetected in the depths of the oceans.
- Fishermen Terrified by Giant Shark: In 1918 an Australian naturalist named David Stead recorded events when local fishermen refused to go back out to sea after an unbelievably massive shark had demolished their gear and taken their catch. These were experienced men of the sea, familiar with whales and large sharks, but whatever they had seen had frightened them so much that they refused to work. According to Stead, they described it as between 35 and 90 meters long and pure white in color. These proportions seem unbelievable. Could a shark really grow to that size? Were these men exaggerating? Or, were they just confused?
- Massive Shark Threatens 55-Foot Fishing Boat: In the 1960s, the captain of a 55-foot fishing ship reported that a white shark at least as long as the boat passed by while they sat at anchor. The crew refused to officially discuss the sighting, but the Captain gave his account. An experienced sailor, the Captain would have been able to recognize a whale if that is what it had been, but he claimed it was indeed a giant shark. Are stories such as this one based on real encounters, or are they just products of the imaginations of sailors who have been at sea too long?
The Biggest Shark that Ever Lived
All of these sightings and stories are interesting, but are they really enough to suggest that this massive shark is still alive? Is it still out there somewhere, stalking the oceans of the world? Is there any reason to worry about going into the water at the beach?
If it makes you feel any better, it is pretty unlikely. Mainstream science is unmoved by the evidence supporting the possibility of megalodon’s existence today. Still, the idea of this monster shark out there patrolling the ocean deep is fascinating to imagine. There is still so much of the ocean left unexplored, the possibilities are almost endless.
The Megalodon Poll
Questions & Answers
Question: Was megalodon a dinosaur?
Answer: No, the megalodon shark was not a dinosaur. While there is some debate, megalodon is classified either within the genus Carcharodon or Carcharocles. Under Carcharodon is would be considered a relative of the modern great white shark. Under Carcharocles it would have been the last remaining species of big-toothed sharks.
Either way, the megalodon was a shark, not a dinosaur.
In fact, megalodon didn’t even live at the time of the dinosaurs. While there were prehistoric sharks back then, megalodon did not evolve until around 23 million years ago. The extinction that wiped out the dinosaurs occurred 65 million years ago, putting a 40-million-year gap between megalodon and the last known dinosaurs.
While meg may not have been around back then, some of its relatives were. Otodus was a massive, 30-foot shark and, while not as big as megalodon, it was a formidable ocean predator. There were also terrifying marine reptiles such as Liopleurodon, and Shastasaurus, which grew to the size of a megalodon shark.
Question: Did the megalodon shark have any predators or enemies?
Answer: The megalodon shark was an apex predator, meaning it was at the top of the food chain. Apex predators have no natural predators of their own, so a fully grown megalodon had little to fear in the prehistoric oceans. It was the big boss of the ancient seas, and it hunted a wide array of prey items.
However, even apex predators end up on the wrong end of the lunch menu now and then. Modern great white sharks are apex predators, but they are sometimes hunted and killed by orcas, another apex predator. So, it isn’t unreasonable to think this could have happened to megalodon.
But orcas are larger than great white sharks, and they hunt in packs. What kind of animal could have taken on the massive, 60-foot megalodon shark?
<i>Livyatan melvillei</i> was one contender. It was a whale as big as an adult megalodon shark, with foot-long teeth. It, too, was an apex predator, but would it have taken on meg in the right situation?
It’s impossible to know for sure, and because shark skeletons are made of cartilage, not bone, we have no megalodon bones to reference for bite marks. Nevertheless, it is intriguing to imagine these two prehistoric hunters squaring off in the ancient ocean.
Question: How big is a megalodon shark?
Answer: The megalodon shark could reach a length of up to 60 feet, according to current estimates. This is much shorter that earlier estimates, where some researchers speculated megalodon might have been 100 feet long. That’s as long as a blue whale!
Still, a sixty-foot shark is a really big fish. To put this in perspective, a very large great white shark may reach an adult length of 20 feet. Megalodon was three times as big!
Megalodon may have weighed 50 tons, with some estimates putting them even heavier. Again for perspective, realize that the largest great whites are around 5,000 pounds, or about 2.5 tons. Any way you look at it, Megalodon was a really huge shark.
It’s important to realize that researchers can only estimate these numbers, as no living megalodon or carcass has ever been found. Sharks skeletons consist mostly of cartilage, so megalodon doesn’t leave much behind.
However, there is an abundance of fossilized teeth, and a few fossilized vertebrae. The largest megalodon teeth are over seven inches long, where a great white tooth is between two and three inches long.
Comparisons with the great white give researchers a rough estimate of the size of the megalodon shark. If more information becomes available, those estimates may change.

the magalgdon was the biggest shark in the world
alexis on July 11, 2020:
Thank you for sharing but i think this isnt true. Only a bit of the ocean has been discovered. Probably like 15% or 25 percent is discovered? That leaves 85 or 75 percent still undiscovered. we dont know whats in those places so, There has to be atleast a few megladons in the ocean somewhere. Again thank you for sharing this article about Megladons! have a wonderful morning, evening or after noon! Dont give up on your dreams :)
Carrie Lee Night from Northeast United States on May 10, 2020:
Thank you for sharing :) Logically, I think it is extinct, however the ocean is too vast to know for sure :)
unknown on April 23, 2020:
its still alive
Gundeep Kaur on April 15, 2020:
I believe that Megalodon still exists in the deeper end of the oceans. I would be fascinated to see a megalodon.....
Wesley on March 31, 2020:
they are still alive.i know for sure down near the arctic.
Sarah on January 31, 2020:
we've actually only discovered 25% percent of the ocean, my theory is that all the deep sea trenches like the Mariana Trench, are all connected to a cave system that larger and rarer species we believed to be extinct, are hiding in. after all there is 75% of the ocean we haven't even physically been on
Emily on December 27, 2019:
There is a possibility that they could still be alive today. We know so little about the ocean and it's creatures that there is a great chance.
MrBeast ( just a fan ) on December 25, 2019:
It COULD still be out there. Us, Humans, have only covered 5% of the oceans. There is a chance. We jut have to look for it and stop being Scarredey-Cats.
Anthony on December 12, 2019:
I think that the megalodon is still alive because only 5% of the ocean has been discovered and megalodons live at the vary bottom of the ocean so there could be just maybe be the perfect buffet for the megalodons down there.
Bella on August 08, 2019:
I think they are still alive I don't know. only 5% of earths oceans waters has only be discovered which leaves 95% unexplored so it might be likely they the Megalodon and other sea animals that are claimed extinct ocean animals may still be alive.
Tom on July 22, 2019:
With us still only knowing so little of the ocean itself, it's complete ignorance to think that the megalodon no longer exists. As far as food and climate change I'm pretty sure the shark is capable of swimming towards it's comfortable climate as well as a plentiful food source. Plus yes it was warmer back then but it was still colder in lots of parts of the ocean so how do we not know that it didn't prefer colder waters to begin with. So yeah we can throw that assumption out the window. In my opinion with the facts and statements given the Megalodon could or is very well still alive somewhere out in the deep blue waiting for its opportune moment to shock the world.
jack on June 20, 2019:
back in 1976 I was living in stamford ct. we kept a 35' luhrs sport fishing boat at stamford marina..We made numerous trips to montalk during the summer months and fished off shore about 30 miles out of montalk on one of our trips we thought we spotted a large whale. We soon realized it was NOT a whale since no whale i have ever seen has a dorsal fin. This creature was easily 20' longer than my boat. I do not profess to know what it was,but it seemingly was not interested in us and left the area . The depth at that area was about 600', Shallow by ocean standards .to this day I have no clue as to what it was. I am fairly certain it was NOT a whale..that was the only time in my more than 50 years fishing the ocean that I have seen anything like it !
Nicholas Tate on May 06, 2019:
It is still alive and I know it.
Kaniah on April 11, 2019:
But, if 95% of the ocean is unexplored, then how do you know?
Also, 99% of the bottom is unexplored.
MrTKennedy1981 on February 20, 2019:
Truthfully, the answer to this question is simply common sense: NO IT IS NOT ALIVE.
Yes the oceans are very deep, with the Mariana Trench being over 7 miles deep, it is the deepest KNOWN point in the oceans. Also, think of the massive diet and amount of food it would require to feed that behemoth! And with all the technology we have and all the ships and sonar and submarines on the water....SOMEONE WOULD HAVE SEEN IT AND RECORDED IT ON VIDEO; by video I mean REAL evidence instead of all those bullsh*t photoshopped and misidentified sharks the kids see on youtube now.
Megalodon would have long made itself known, as this creature would be massive and ocean life would be acting very cautious and terrified of this thing.
Would I like it if it were alive? YES YES YES!
But is it alive? NO NO NO.
dave on January 24, 2019:
that was very cool
mason on December 29, 2018:
I thing the meg is still alive I Look it up on google it did not say any thing about the meg being still alive.
Kristy on December 14, 2018:
It’s in the Maraiana trench it’s not alive anymore
jaycub on December 13, 2018:
megalodons can still be alive because 71% of the ocean is undiscovered so if they don't discover that there is no proof that they are extent.
Izzy on November 17, 2018:
The megalodon shark is still alive. It could be in the Burmuda triangle.
Me on November 17, 2018:
Well, The movie The Meg might be fictional, It might actually have some true facts in it. But I think from based off the movie, That there might be a cloud and if we go up that cloud, That will allow a Megalodon to come up that warm water. So therefore, I think the megalodon still exists deep down about 12,000 meters But, We still have only discovered 5% of the ocean, so It doesn't have to be all the way down, Just a theory.
Autumn on November 16, 2018:
I think its still alive
Daniel on September 27, 2018:
Over 90% of the ocean has yet been discovered so therefore I. Believe the Meg still exist.
Nick Follis on September 13, 2018:
the megalodon is still alive in the bermuda triangle

Is a megalodon stronger than 100 te-Rex
dragon on August 19, 2018:
i vote on the possibility of the megalodon in the deep after all we have discovered more of the moon then our oceans
Eric on August 19, 2018:
For Robert R Wynn , the black and white photo that you are mentioning unfortunatley is a fake , I know of which picture you are referring to because it was an obsession for me for awhile until I read something online or watched a you tube video about the picture but I belive that Megs still exist anything is possible. Yeah I was disapointed when I found out sbout the picture being a hoax the person goes into depth about and showing the original photo without the tail and fin in it and also the emblems and insignias on the boat were added or changed or altered also ...sorry to bear the bad news .
Sumit on August 11, 2018:
Did we have any solution to find out that this megalodon shark still exists...
karma on August 10, 2018:
I love dinosaurs but we are so lucky it is extinct because if it was still alive half the people who love swimming in the ocean would be dead

The Meg with Jason Statham is set for release on August 10, 2018. It's based on the novel by Steve Altman. I'm pretty interested in seeing it too. Not sure when I will, but I'll either be posting a review or updating this article. I see most movies at home so it may be awhile.
In the trailer the shark looks much bigger than current megalodon size estimates, though everything I read says its 70-75 ft which is on the high side but in the ballpark. What the heck it's just a movie.
anominous on August 05, 2018:
Cant wait for the meg movie its going to be jaw dropping
Valerie on July 14, 2018:
i still think megalodon exist biologist hasnt found proof that it didnt die marine biologist needs to take a miniture sub to the depths of ocean floor for evidence of exstintion
Navija on July 04, 2018:
This animal is a killing machine
Robert R Wynn on June 29, 2018:
Germany took a picture during ww2 of a U-Boat and A shark next to it It was as long as the boat
Gary on June 28, 2018:
Magaladon possibly still be alive I have been hooked on meg ever sin e I was 5
Dennis on June 18, 2018:
Still waiting for the MEG movie with Jason Stattums!!!! Won't be long now.....
Armand on May 30, 2018:
Due to the drastic reduction in oxygen it is possible that megalodon still exist but is significantly smaller then it used to be. But denying the facts that it could not exist is absurd considering we literally don't even understand a tenth of our own oceans
mystery girl on May 01, 2018:
if it's out here give me a heads up so that i'm prepared to survive at the beach next summer .but hey,sharkbait is right.we humans don't know about the other dangers in the sea, we have to keep our eyes open.I beleive

sharkbait on March 27, 2018:
with only 5% of the oceans explored..the thought that the megalodon is extinct is completely arrogant..i hope im alive when one is rediscovered if they are still out there
Tonionitoklan on March 13, 2018:
There are massive sharks in our oceans, like the six-gill in the Mariana Trench and the Greenland shark. Megalodon could easily have adapted to deep sea life and survived in fewer numbers. What if they can survive cold, but do better in warmer water, and us heating the planet up is just making better conditions for it? The megalodon could have evolved into the six-gills or Greenland sharks. As stated many times, we haven’t explored much of our oceans, and their could definitely be some kind of massive animal out there. :)

just saying, great whites do eat dead whales so that explains the half of a whale
MB on December 14, 2017:
Can scientists explain how half of a blue whale washed up on the shore of Hawaii when that would be a megalodon 's main prey?
Yay! I can try again! on November 28, 2017:
I believe Megalodon still exists as the only reasons for it to have gone extinct is the cold, and hunger due to prey migration. However, if its prey can adapt to the cold, why couldn’t the Megalodon? Also, it could have simply followed its prey, or adapted to the deep, hunting colossal squid and the sperm whale to this very day.
Shark on November 25, 2017:
I think it is possible.

Why didn’t you authorize and publicly post my comment?
lolno on November 16, 2017:
No its not out there I'm stunned at how many people are suckered in by this. For it to still be around it would have to be in significant numbers to keep the population going. Young ones lived in shallow regions and would be sighted easily and adult fed on whales, of which we have never found any remains of giant shark attacks. They also did not and could not live in the trench. The "sightings" produce no evidence, not a shred. The teeth found by HMS Challenger were found in the arctic, somewhere they could not survive and they were preserved by the cold not fresh. This article mentions it but its now mostly accepted they were NOT related to great whites. I know its nice to be carried away in this stuff but theres plenty of REAL things to fear in the oceans. Like killer whales, the things that knocked megalodon off its perch.
MEgy on November 01, 2017:
Very well written article! Good job! I believe that there could be a Meg out there, but this article made me afraid of water haha!
Some Goon on October 27, 2017:
Everyone here is a goon saying that Greenland sharks are as big or that whales are going extinct because of megalodon. Wrong facts.
e5 on October 13, 2017:
Its actually Greenland sharks their massive almost as large as megaladons.
ksclmsmklsckskln on September 19, 2017:
its very possible weve only explored 2 percent of the ocean
Learning with Interest on September 17, 2017:
From what I've Seen and Thinking or my believe that the Megalodon is still alive...Since we only explores 95 percent of the ocean it's still more to explore rigth?I Started asking myself why this blue whale,Sperm whale,and other more whales are going to extinct?!WHY?!IT'S VERY IMPOSSIBLE that those Whales Extinct for no reason rigth?Maybe because of the mother Nature or the GLOBAL WARNING?! I Don't think so...If it's because of the Temperature...They can just move or find another place that we're they can adapt the Climate/Temperature For me I realy Believe that the Megalodon is still Out their somewhere Hunting and Eating smaller creatures.
MAUSIZU on August 27, 2017:
Great article. Plausible that Megalodon is still lurking in the depth of the ocean. The mariana trench is almost 11000 meter deep so there is enough space for it.
Wayne on August 16, 2017:
I believe it is still alive, just about 30-35 feet long. Marine Biologists claim Great White's cannot reach lengths of over 25 feet, not possible. I have personally seen a "great white" dwarf a 26 foot Chris-Craft, and seen a few shows that show a great white at 32 feet. If Whites supposedly don't get this big, what could it be? Has the appearance of a white, but, much, much bigger! Don't be surprised if they are still out there, just smaller now.
darkprose on August 08, 2017:
I wanted to say that my last post was too dismissive. And if the point of all of this is to admit that one cannot absolutely prove a species is extinct, then I agree. That said, I do not think there is any reasonable doubt as to C meg's extinction at this time.
GoldenSolare on August 08, 2017:
I still think there still a megalodon out there we just got to go deeper in the ocean
darkprose on August 07, 2017:
What bothers me the most about all of this is that people would rather spend time fantasizing about things that do not exist when there are all manner of fantastic and mysterious and weird things that DO exist. Real scientists are involved in the real labor of discovering, classifying and understanding real animals, insects and microscopic organisms all across the world, adding to our appreciation of the world as it is. Looking for things like this is not that. Sure, it's fun, but it has no scientific value whatsoever. I wonder how much your commenters know about ACTUAL shark species, of which there are hundreds and hundreds. There is more than enough mystery to them to satisfy a curious, hungry mind. So this turning to purely speculative and mythic creatures is rather dismal.
darkprose on August 06, 2017:
There are anecdotes about giant sharks, yes. Did they see large sharks. Probably. Are the sharks as large as they have said it was? There's no way to know. But we do know eyewitness testimony is unreliable. What's the best explanation that accounts for the facts, which are: C megalodon disappears from the fossil record completely around 2.6 Ma; stories and legends and accounts of gigantic sharks are told by some people, written in fiction and nonfiction, used in mockumentaries (and some dubious documentaries, like MonsterQuest)?
We'd want to posit the least amount of unknown variables and assumptions. I think the best explanation that accounts for what we know is that C megalodon is extinct and exceptionally large and rare white sharks are seen from time to time, while other species, especially the basking shark, are misidentified. Add to that the unreliability of eyewitness testimony, outright hoaxes, and pure and simple lies. Despite the claims, no physical evidence has been found to support the hypothesis that C megalodon is still around. And the fact that it leaves the fossil record completely cannot be explained if this massive fish were still predating in the oceans. We should be finding fresh teeth, like we do for C megalodon's distant relative, the white shark.
Reece on July 29, 2017:
Are the megalodon sharks still alive
Casey on July 25, 2017:
I believe that the Monster Megalodon is still stalking the oceans out there. I often thought about the possibilities of it still alive.

I read the article and watched the video. I believe the Megalodon survived extinction and has adapted to a lifestyle that has enabled it to live virtually undetected in smaller numbers.
Guess on July 13, 2017:
I bealive that some of the creatures or animals that live in the oceans that we humans thought were extinct, may be still alive in the deep ocean. For example the megladons may still roam around the ocean but most of the time hiding because they may be afraid because they think they are going to get hunted down. Also the photographers may be keeping the photos to them selves because they may care about the environment and afraid of getting them extinct.
Lucas on June 21, 2017:
I do belive the megladons still exist just why would that not agree that have plenty of evidence about it and that said it might come out at night at least closer to the surface and that can search that also said it could have adapted to cold climate cheap colder areas then cheap all the warmer areas and if worse comes to worse cheap marinas trench I think that do indeed exist
PHILLIP on May 27, 2017:
Personally, I doubt if this ever gets answered by anyone but this is my belief on the idea of megalodon existing or ever coming back to show itself to anyone, nature has an incredibly strange way of fixing itself. We, as human beings, think that we can wipe out this creature or that creature and not worry about the results. I think that if we continue to kill off certain animals that others will eventually take their place. My proof of this is the dinosaurs, then the prehistoric animals that followed. If we continue to kill off the animals that we have on this planet right now, nature will develop new ones and personally I do not want to see 65 to 70 foot creatures walking the Earth or swimming through the ocean again. That's one thing that we do not need.

Scientists are saying the ocean temperatures are increasing, this might signal a comeback.

I am really into megladon sharks
blablabla on April 09, 2017:
Theres no way that the megalodon exists as it was much hotter in the past
Robin on March 26, 2017:
Megalodon is out there somewhere, I mean even if there's not an actual "megalodon shark" that doesn't mean that there is none... For instance, scientists believe that megalodon closely resembles our modern day great white sharks with the main difference being the tremendous size of the megalodon. Now.... This is my theory, what if megalodon shrank over their evolution and what if now it is actually the great whites that we see today?
Noah on March 24, 2017:
Thanks so much I am doing a school project on this this was so helpful thanks so much
Aarya on March 23, 2017:
Yes , I think megalodon shark is alive but one of my friends said it is extinct
hasnaintariq on March 06, 2017:
megalodon is still a live we need to search it.its a big discover
1987 on February 14, 2017:
Yea I'll bet there is one or two left!
The Beast on February 07, 2017:
there is no way this shark can still live. It was dead billons of years ago we the astros struck the earth
comment winner on February 01, 2017:
Megalodon IS alive i saw one it was 100ft.
Tony on January 26, 2017:
Your article was extremely informative. It also had my attention the whole time! The idea of this monster still existing is fascinating. My father is from Cuba and have heard many stories of weird sea creatures from him!

this seems very scarey not sure im gonna swim at the beach anymore
thank u for this info
Byron on November 30, 2016:
Thx for posting this cryptid, it really makes my imagination explode with different thoughts about the shark.
flfl on November 26, 2016:
good evidence but megalodon is alive
DCDOOMSDAY on September 27, 2016:
I have a theory about the submarine shark. My theory is that the submarine shark is a baby megalodon and is still growing . Also , the reason I think that is because the megalodon's prey went to colder areas in the world and adapted to the cold climate and the megalodon didn't have any food to eat and that caused it to die. So we humans were being stupid and releasing chemicals into the stratosphere and damaging it and in doing so that made our climate warmer and that gives the megalodon a chance to repopulate and that might of happened that is why people report seeing a so-called submarine shark. If my theory is right then we just released really , really , really , really DANGEROUS.
FrizzyPhillips on September 07, 2016:
Ive been into Megalodon for some time now and in my opinion still think its lurking in the waters. Thanks for this article on Megalodon. it really helped me understand more about the shark. There has been numerous sightings of Megalodon captured on footage that I have been trying to figure out if the shark in the video is Megalodon. So far im still finding new things to do with the shark itself. There have been sharks in Britain for a while now and im starting to think what could be in the depths of our oceans.
Sam on September 03, 2016:
Its good to see how thoughts develop into theories . If u believe in something so much it will come to life. who knows anything about MEG color size and characters... its evolved and any big shark undiscovered can be megadolon . It needs to be big and cool
Jee on September 03, 2016:
Megalodon is over and extinct. Don't waste ur time in crazy fantacies.
Prateek Chellani on August 30, 2016:
The real problem is that we actually have zero proof for any existence of the megalodon. But that doesn't really stop us from speculating again :D This might just turn out to a case similar to the coelacanth, where even though there is proof, none of it has been documented, since there was no incentive for locals to report the incident. Maybe if we start putting out monitory rewards for people providing clear images/ or any other proof....
Also, I did read your article, and while it is evident that the Marina Trench is a possibility, I feel it may not be the only possibility.
While there isn't a lot of food options down there, I feel that an occasional Sperm Whale or a couple of squids may help a meg survive. It has been observed that great whites can survive for more than 2 months on whale carcasses. While the meg is larger, I feel it may also be more efficient at hunting down it's pray, so may need to spend lesser energy.
Also, we don't actually have any idea of the reproducing pattern of the meg. It may be that reproduction produces only 1-2 young or so, just enough to sustain the population, without causing an increase or decrease.

Hi Prateek. Thanks for your thoughtful comment! It's an interesting theory with some compelling ideas, but also a few holes. I actually wrote an article about it a few years back called Does the Megalodon Shark Live in the Mariana Trench? You can find it on this site.
In my mind, the main issues comes down to whether there is enough food at those depths to sustain a population of Megalodon. Meg is believed to have been a coastal hunter, like the great white, so it would have needed to completely change its hunting strategy to evolve to live at such depths. On the other hand, great whites have been shown to dive fairly deep, and even prey on creatures like giant squid. If only a small population of megalodon had already it evolved to hunt and live at great depths, when the rest went extinct this small population may have survived.
Of course the real problem is we have zero proof of this, but it is interesting food for thought.
Prateek Chellani on August 25, 2016:
This is a one of the best articles I've read debating the existence of the Megalodon.
I've been reading and researching about megalodon sharks for almost 4 years now, and I really can't accept that they are extinct. Sure, no evidence of its presence has been found, but Absence of Proof is Proof of Absence.
A theory that seems rather appealing to me, is that the megalodon still exists in greater depths. As you mentioned in your article, the reason for extinction probably could be newer, smaller predators evolving to occupy the niche of the Meg. If that is the case, it is possible that few Megs started diving to deeper depths away from competition. (Few individuals within a certain species evolving to learn new techniques isn't a new phenomenon, best documented example is that of some Killer Whales propelling themselves on to shores to hunt for seals) It is quite possible that a some individuals moved into the depths, and have established a large population now. They probably never needed to come towards the surface anymore, since not a lot of other predators can survive in the depths due to the high pressure. The meg probably evolved to be able to tolerate such pressures. Further, one of the large cetaceans that lives in the depths is the sperm whale. Multiple sperm whale carcasses have been found on shore, killed due to attacks. Many of them have beaks marks suggesting attacks from squids, but there are few which end up on the beach fin-less. It is debatable if these could be due to an orca/ great white or a meg. There is no documented report stating the cause of the loss of the fin, and no report even claiming to have examined bite marks left behind.
As you mentioned in your article, the only proof of existance of the giant squid we had was the washing up of bodies on shore. There could be a reason why Megalodon bodies haven't washed up yet - cannibalism, a scavenger at the bottom of the ocean, etc. Similarly, if the body was consumed before it reached the surface, any teeth that were left behind may have sunk to the depths of the ocean. Alternatively, we have no idea about how often megs reproduced or how many young ones they gave birth to. It is quite possible that population that migrated to the bottom of the ocean hasn't grown for millions of years, and that is probably why we still can't find any evidence for their existence.
This is just a theory to think about, and it seems quite possible to me that this legend is far from extinct. I'd like to know your views on the theory @cryptid
cryptid (author) from USA on July 27, 2016:
@Frank: The show contained fabricated and fictional material. There is no widely accepted proof that Megalodon exists today. However, Megalodon did once really exist long ago and some people think it is still out there based on what you've read in this article.
Frank Juarez on July 26, 2016:
I just watched Megalodon: The Monster Shark Lives and I was so convinced with this and I want you to tell me if this is real or not cause I can't keep this question out of my head
Mason on July 24, 2016:
I think the megalodon is real I have been studying it for a while now and have looked at loads of sightings and the odds are of megalodon being alive still are pretty high.
Luvinsharks on July 04, 2016:
I don't want to see fictional anything when it comes to sharks or Megalodon. I just like when they get new footage of never before seen behavior that makes you say wow that's cool. Most footage I saw was of behaviors already known. I do love learning of white sharks migrations and see how far tagged white sharks travel. My favorite thing this year was seeing how all sharks react to the pheromones of dead sharks and how when they smell it they disperse immediately. It could be used as a new shark repellent or the scent that the American crocodile puts off and how they used it when they were studying bull sharks and they made shark repellent with it and it made bull sharks totally leave the area almost immediately!! I hope they start making those shark repellents for divers and surfers or anyone who is in shark waters. It could easily save their lives. As always I learned a bunch from shark week. It's still the best week of the year!!
