The Megamouth Shark

The megamouth shark (Megachasma pelagios) is a massive species of shark that's rarely seen by humans. In fact, since its discovery in 1976, there have been relatively few live sightings. It is big, elusive, and very strange.

Megamouth sharks can grow nearly twenty feet long, the size of a very large great white shark. But there is no reason to fear getting chomped by this monster of the deep. Megamouth is a filter feeder like the whale shark and basking shark. These sharks don't attack prey but instead swim with their mouths agape, sucking in tiny organisms.

Megamouth may be big and weird, but unless you're an ichthyologist it may also seem a little boring. What kind of fun is a shark that doesn't bite?

Then again, if you are a cryptozoologist there are a few things about this mysterious sea creature that make it pretty darned interesting.

In this article we'll take a look at the megamouth shark, and what it all means in relation to other mysterious sea creatures. Does the existence of the megamouth prove there are more monster sharks out there, awaiting discovery?

Massive Great White Sharks

Legend has it there are some massive sharks out there. Some people claim to have spotted great whites measuring 30 or 40 feet. Of course, they didn't actually measure them. They spotted them from a boat, and that immediately calls these accounts into question. However, such sightings often come from experienced fishermen who ought to know how to estimate the size of a swimming shark.

Then again, you know what they say about a fisherman's tales, especially regarding the ones that got away. The largest great white ever officially recorded measured over 21 feet. So why should we think these stories of massive great white sharks are anything but exaggerations?

It's reasonable to think that if great white sharks do reach such large sizes they would be spotted and documented. However, the fact that the megamouth shark grows so large and is so rarely seen is something to ponder.

How does such a massive shark go undetected until the 1970s? This isn't a small fish or invertebrate, or even a medium-sized fish like the Coelacanth, which was once thought extinct. This is a massive shark, yet even today, with our modern technology, encountering this behemoth is extremely rare.

Because the megamouth is so rare there isn't enough data to calculate their exact numbers. It may, in fact, be an endangered species. But even so, it's probably safe to say there are more megamouths in the world than there are 30+-foot white sharks.

If the megamouth is out there and so hard to document, isn't it possible there could be massive great whites out there as well?

Or, even something bigger.

The Megalodon Shark

The megalodon shark went extinct millions of years ago, but some cryptozoologists still think it is still around today. At a length approaching sixty feet, you'd think it would be tough not to notice if it were really out there, but some believe megalodon might exhibit behaviors that make it even more elusive than the megamouth.

Some say megalodon, if it is still around, likely lives in very deep water such as the Mariana Trench. Here we see a few ways the megamouth shark can help to bolster this idea.

One of the reasons the megamouth remained hidden from science for so long was because it is believed to exhibit a pattern of diurnal vertical migration. This is where a sea creature stays in the depths during daylight hours, then comes closer to the surface and even into shallow waters at night.

In the case of the megamouth, it is following small organisms such as krill, many of which migrate from the depths to the surface at night.

As for megalodon, we may speculate that it is following larger prey items like a giant squid. Or, perhaps it preys on some other large, unknown creatures. If megamouth is so rare, who knows what else could be out there?

Of course, this isn't nearly enough to say megalodon is still out there, but the fact that a large shark like the megamouth could elude marine biologists provides a little food for thought.

Ocean goers once feared strange sea monsters lurking the depths. Were they right to be wary?

Sea Monsters

What else could be out there? Sailors and sea goers claim to have spotted sea monsters for as long as people have been traveling the ocean. Is it possible that some of their stories could be true?

From Mermaids to Lake Monsters, strange creatures always seem to come attached to large bodies of water, and the ocean is the largest body of water of them all. Much of it is unexplored, even in modern times.

So, are there sea monsters in the open ocean? That depends on our definition of "monster". Even the most skeptical of minds has to admit there may be unknown large creatures down there, awaiting discovery.

The first recorded megamouth encounter in 1976 may seem like it happened a long time ago, but in terms of how long mankind has been documenting the ocean, it was really almost yesterday.

It's also worth noting that the second documented encounter didn't occur until 1984. This highlights how easily a species can slip past our detection, even after we know it exists!

We have to assume any large, undocumented creatures must live in fairly deep water, or in remote parts of the open ocean. They likely occur in areas people rarely frequent, because to do so is either dangerous or simply impractical.

Like the discovery of the megamouth shark, encountering them will most likely be a matter of luck and circumstance.

Facts vs. Speculation vs. Hope

Does the tale of the megamouth shark prove massive great white sharks, the megalodon shark, or even sea monsters really exist? Does it mean there must be fantastic monsters lurking in the dark of the sea, waiting to be discovered?

Not even close, but it does offer some interesting ideas about how vast, unexplored, and mysterious the ocean really is.

Progress is often governed by money, either the quest for it or lack of it. Explorers who would set off in search of rare sea creatures in deep or remote parts of the ocean need massive funds at their disposal. Running an ocean-going research project takes big cash. Searching for sea monsters simply doesn't bring in the money.

On the other hand, large companies who think it is worth their while may be motivated to explore remote parts of the sea in search of mining or other resource-related opportunities. Though they might not be looking for them, these big companies with lots of money behind them may have the best chance of discovering such creatures. Hopefully, they don't harm them first!

This sounds a bit ominous, but really it is a good thing. It gives us a reason to believe these discoveries might actually happen, and any day there may be news of something fantastic. The ocean is deep, and if nothing else perhaps the megamouth shark gives us hope that there are still amazing creatures out there to discover.

Good article. Since there are many eyewitness of massive great white over 20 feet in length there wouldnt be that strange if all the big ones actually was Megalodon. If there is a small population I could definetaly see it exist. I think its size and ferocity makes it extremely hard to fish out of the sea. How often do you see an almost 20 feet great white laying stranded on the beach? Never. And that is probably because they are the master and kings of the sea. It can also mean another thing. Since it probably would lurk pretty deep in the ocean it would less frequent than other animals getting troubled by the wawes. If someone searched more in the depths of the mariana trench they could maybe find a teeth or two from a not dead long ago Megalodon!, but the sea floor would probably have been cleansed already by the secret government;)

Another question we must ask ourselves, is if Megalodon still lives or if these sightings just are extremely massive Great whites. Who would benefit of keeping it a secret?

I believe there must still be many things in the water we don't know about.

Thanks for the kind words, Jeb!

Very impressive!!! I like your plethora of knowledge in terms of ocean life that lives out in an area where humans know so little about today. Good job.

Thanks poppyr. Personally, I'd like to see major advances in the both the study of space and the deep ocean. Not only will the discoveries prove incredible, but the technologies that must be developed to explore remote places often trickle over to other fields. We'd all see a benefit down the road in fields like medicine and computer science.

Good article. I've always been fascinated with the ocean. I agree with Sheila on that people do argue we need to stay space, yet we don't even know everything about the world underwater. I very much doubt we've discovered everything in the big blue.

cryptid (author) from USA on July 04, 2014:

Very true, Sheila. Hopefully if it's a rare species it can be immediately protected through agreed upon international conservation laws.

I believe there are still many things, large and small, in the oceans yet to be discovered. I know people who argue we need to study space, but I wish that money was used to study our oceans in more detail. Then again, rare species or not, as soon as some people find some new and interesting, they hunt it for trophies and more things become extinct.
