Mitsukurinidae is a family of sharks with one living genus, Mitsukurina, and five fossil genera: Anomotodon, Protoscapanorhynchus, Pseudoscapanorhynchus and Scapanorhynchus, Woellsteinia[1] though some taxonomists consider Scapanorhynchus to be a synonym of Mitsukurina.[2][3] The only known living species is the goblin shark, Mitsukurina owstoni.

The most distinctive characteristic of the goblin sharks is the long, trowel-shaped, beak-like snout, much longer than those of other sharks. The snout contains sensory organs to detect the electrical signals given off by the shark's prey.[4] They also possess long, protrusible jaws.[5] When the jaws are retracted, the shark resembles a grey nurse shark, Carcharias taurus, with an unusually long nose.
