Mitsukurina owstoni, or Goblin Shark, is the only remaining representative of the Mitsukurinidae family of sharks, that originated at least 125 million years ago, and often referred to as living fossils.The Goblin shark has only been encountered a few times and very little is known about it. What is known is that it is a slow moving deep sea shark that lives at depths of 1200m/4000ft in seas around the world. Goblin sharks have been observed in the western Indian Ocean, western Pacific Ocean and most of the Atlantic.
They are known for their strange specialized “catapulting” jaws, which almost looks like there is something that lives inside of the sharks mouth that explodes outward to catch prey before returning back into the mouth.
