Goblin shark

Goblin shark, Mitsukurina Owstoni

The shark is thought to have been feeding on some sort of animal life growing on the cable at that depth, but very little else is known of its feeding habits. Its awl-like teeth and protrusible jaws seem to indicate that it is a fish eater, but this is only a supposition; it probably needs protrusible jaws to feed at all, given the nature of its forehead appendage. This seems a self-handicapping situation, so perhaps the protrusion serves some other, less problematical function.

This seems to me the strangest of all the sharks. It looks like some kind of prehistoric survivor, an experiment in shark design that doesn’t seem to work. And yet, but definition, it does work.
