Range of combtooth dogfish (in blue)

The combtooth dogfish (Centroscyllium nigrum) is a little-known, deepwater dogfish shark, named after its teeth that are comb-shaped.

Description

[edit]

The combtooth dogfish has no anal fin, grooved dorsal spines, two dorsal fins of about same size, a pointed nose, large eyes, small gill slits, a short abdomen, a short caudal peduncle, and is blackish-brown in color with white-tipped fins. Like all dogfish sharks, it has 2 spines in front of its 2 dorsal fins. It grows to a maximum of 50cm. It has a faint tiger-like band held together by the lateral line that has photophores that emit light to attract prey. Immature pups are born at 11-13cm. It has a spiracle behind each eye.

Diet

[edit]

It consists of eating small fish, shrimp, and cephalopods.

Habits and Habitat

[edit]

It is an uncommon deepwater shark found close to the bottom between 400 and 1,145m. It is found in the eastern Pacific and around Hawaii.
