20 Amazing Facts About Megamouth Sharks

Buckle up for a thrilling ride through the enigmatic waters where sharks rule the deep blue. Together, let’s unravel the mysteries and dive into the fascinating world of their incredible features!


1. Hold onto your fins – did you know the megamouth shark’s full name is quite the tongue-twister? It goes by Pelagic Pelagicus, or Megachasma pelagios in the Latin sea of words. Translated, it means «Living in the depths of the vast abyss.»

2. Meet the heavyweight champion of the deep – the megamouth shark. Stretching almost 6 meters long, it’s a one-of-a-kind oceanic giant.

3. Brace yourself for a jaw-dropping fact! What sets this abyss-dweller apart is its rounded head sporting a colossal mouth. Believe it or not, the head alone can match the length of the rest of its torso!

4. Prepare for a scare – the megamouth’s terrifying look comes courtesy of its jaws that jut forward, adorned with a collection of small, razor-sharp teeth.

5. In the fashion world of the deep sea, the megamouth shark rocks a dark brown ensemble on its back, keeping it incognito in the water column. But flip it over, and you’ll find a more light-colored belly – talk about underwater camouflage chic!


6. Talk about elusive! The megamouth shark is like the ocean’s ninja – it’s been spotted in every ocean except the Arctic, but always as a surprise guest. Human encounters? Just a handful, making it impossible to pinpoint its exact stomping grounds.


7. Not every shark is on a fast track, and the megamouth is living proof. It’s the chill, laid-back friend of the sea, sporting a loose and flabby physique that screams, «No need to rush, mate!»

8. Need for speed? Not in the megamouth’s vocabulary. Cruising at a leisurely 2 kilometers per hour, it’s in no hurry – after all, krill won’t be pulling any disappearing acts!

9. Ever wondered about a megamouth’s daily routine? Scientists are still in the guessing game. The likely scenario? These oceanic giants probably pull a night shift, hunting between 10–25 meters deep, and then take a deep-sea nap around 150 meters during the day.

10. Fun fact alert! The megamouth isn’t the only star in the sea – the luminescent Brazilian shark is a big fan. Check out those numerous scars on the megamouth’s body; they’re like battle wounds from encounters with these nimble predators.

Eating Habits

11. Brace yourself – the megamouth shark might give you the heebie-jeebies, but it’s not your typical fearsome predator. Just like its giant cousin, the whale shark, it’s all about that plankton and krill diet.

12. Who knew the megamouth shark could multitask? Not only does it feast on plankton and krill, but it also does a bit of water-filtering gymnastics to ensure it gets the right amount of food.

13. Dive into speculation land! While not confirmed, there’s a buzz that the megamouth’s mouth might be a showstopper, glowing and luring in krill with its luminescent edges. Now, that’s what we call a flashy dinner invitation!

Intelligence and Social Behavior

14. Talk about a loner lifestyle – the megamouth shark is the introvert of the ocean. Every sighting so far has been a solo affair, and its social calendar is pretty much blank.


15. When it comes to family matters, the megamouth shark is a bit of a mystery. They’re in the egg-laying club, but details like gestation length, the number of shark kiddos, and maturation rates are still filed under «classified.»


16. It’s a bit of a head-scratcher, but despite the lack of intel, scientists are feeling optimistic about the megamouth’s future. They don’t have a clue about the total shark population or the threat level – it’s like the ocean’s best-kept secret!

17. Imagine a guest list with just over a hundred attendees – that’s the VIP count for megamouth shark sightings so far. These underwater celebs are truly exclusive!

Danger To Humans

18. Hold onto your snorkels – good news! The megamouth shark is the ocean’s gentle giant. No recorded cases of aggressive behavior towards humans, making it the ultimate sea buddy.

19. Lucky for the megamouth, humans aren’t on its list of worries either. It’s not a sought-after catch, and any accidental run-ins with nets are just oceanic oopsies.

Are There Any Aquariums with Megamouth Sharks?

20. Ready for a reality check? If you were hoping to spot a megamouth shark up close, you might be out of luck. All encounters so far have been unplanned rendezvous across different corners of the world ocean. And don’t bother checking your local oceanarium – these underwater enigmas prefer to keep a low profile!

The story of my interest in sharks.

I am actually afraid of sharks, but at the same time I am attracted to them.

When I was about 10 years old, my mother and I saw the film «Jaws» and I think it really scared me.

So I started this blog and will share what I have learnt about them. I would love it if you could share your shark encounter story with me.
