Giant megamouth shark is a  strange looking deepwater shark, which only few people in the world have encountered. Megamouth shark lives on great depths and it's latin name is Megachasma pelagios. This kind of shark has been discovered recently in 1978 (Hawaii) and only 49 specimens have been caught or seen in the past few years. With a bit of luck people have caught him on tape (3 films). The Megamouth Shark is a shark that doesn't feeds itself with flesh from other animals, but from filtering the water, just like Whale Sharks do. Because of some great differences with other sharks it didn't find any family to join. Therefore Megamouth Shark belongs to its own family called Megachasmidae.

Megamouth Sharks skin is colored in a brown-black color and he is a poor swimmer. Just like the Whale shark, this shark is relatively big and can grow up to 6 meters in length with a weight of 1500 kg. It has a very long mouth with dozens of little teethes and like many deep sea creatures photophores (light giving organs) to lure plankton. The reproduction happens like similar to Whale Shark, the eggs are kept and hatch into the mother's body.

Megamouth Sharks have been found in temperate waters (Japan , Australia, South-Africa, Brazil...) and at least ten specimens have been found in Japan.
