Giant Megamouth Shark (Megachasma pelagios)
The Giant Megamouth Shark is an extremely rare deep sea shark! This species was only discovered in 1978 in Hawaii, and since then there have only been a handful of sightings! It is the lone member of the family Megachasmidae and has been reported only in the deep waters around Japan, Australia, and South-Africa.
Much like the Whale Shark and the Basking Shark, the Megamouth Shark simply swims around with its mouth open which is full with over 50 rows of very small, hooked teeth. It collects food by filtering out the water with its gills, what’s left after the water is drained out is its dinner. Like a lot of other deep sea creatures, they actually have photophores that give off light and attract the plankton right into their mouths!
