The prickly shark, "Echinorhinus cookei", is a species of large bottom dwelling shark from the Pacific Ocean.

Physical characteristics

The prickly shark has no anal fin and two small spineless dorsal fins set far on the back by the tail. Its maximum length is 4 m, and it looks very similar to the bramble shark but without the thorny denticles.

Distribution

The prickly shark occurs throughout the Pacific, including Taiwan, New Zealand, Hawaii, California and Chile, among other locations.

Habits and habitat

The prickly shark lives along shelves and slopes at depths between 11 and 425 m. It is often found in submarine canyons. Other sharks and bony fish are its usual food but it will also eat octopus, squid, and even catshark eggcases. Reproduction is ovoviviparous, with up to 114 pups in a litter.
