Mitsukurinidae is a family of sharks with one living genus, Mitsukurina, and five fossil genera: Anomotodon, Protoscapanorhynchus, Pseudoscapanorhynchus and Scapanorhynchus, and 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.

This family of sharks is named in honour of Kakichi Mitsukuri who bought the holotype of the only species in this family to David Starr Jordon to be scientifically described.[4]

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.[5] They also possess long, protrusible jaws.[6] When the jaws are retracted, the shark resembles a grey nurse shark, Carcharias taurus, with an unusually long nose. Its nose resembles the nose of a goblin, which is how it received its name. These sharks have only been seen about 50 times since their discovery in 1897.
