The distribution of the two Echinorhinus species

Echinorhinus is a genus of Echinorhiniform sharks, and the only extant genus in the family Echinorhinidae. The name is from Greek echinos meaning "spiny" and rhinos meaning "nose". Both species are uncommon, little-known sharks. They are found worldwide in cold temperate to tropical seas down to 900 m (3,000 ft) depth.[2]

This genus includes two extant species characterized by a short nose, rough spiny dermal denticles, no anal fin, and two small spineless dorsal fins. Both species are relatively large sharks, at 3.1 to 4.0 m (10.2 to 13.1 ft) in body length. They feed on smaller fish, and on crabs and cephalopods. They are ovoviviparous, with the mother retaining the egg-cases inside her body until they hatch.[2]
