Description

The swellshark is a catshark from the eastern Pacific, from central California to the Gulf of California and southern Mexico, and off central Chile. The species grows to about 110 cm and has a stocky, yellow-brown body with dark blotches. When threatened it can inflate its stomach with water or air, so that it looks larger and wedges itself among rocks; from this behaviour it takes its name. It is nocturnal, by day sometimes resting in piles, and hunts bottom fish. It lays eggs in horny capsules. The IUCN assesses the species as Least Concern (LC).
