Goblin Shark Mitsukurina owstoni

This horror is a deep sea dweller that lives in oceans all over the world, but it is most commonly found in the waters off of Japan. The shark averages about 9 feet in length, is colored a light pink, and has an extendable jaw that is the thing of nightmares. The clip below shows these jaws in action (skip to 30 seconds).

While not endangered, the Goblin Shark is usually seen only a few times a year, mostly as an accidental casualty of deep sea fishing. However in 2003 over 100 were caught near Taiwan, a short while after an earthquake had occurred in the area. Needless to say 100 of these guys hunting in relatively shallow water is not reason for celebration, so think twice before swimming after any earthquakes.

Finally, I should mention that the Goblin Shark is not considered dangerous to humans; just scary.
