About the Swellshark

The swell shark (Cephaloscyllium ventriosum) is a catshark in the family Scyliorhinidae. It is found in the tropical and subtropical eastern Pacific Ocean from between central California to southern Mexico, with an additional population off the coast of Chile. They are known to have brown and white spots along with broad heads. As a defense, the swell shark is able to expand to approximately double its regular size by swallowing water. They depend on electrical signals to find prey, camouflaging in rocky crevices.

When discovered in 1880, the swell shark was first described as Scyllium ventriosum, but was later changed to Cephaloscyllium ventriosum. The genus name comes from the Greek word kephale, which means "head", and skylla, which means a certain kind of shark. The species name comes from the Latin word ventrĭōsus, which means "large-bellied". The species name refers to its ability to enlarge itself by taking in water.
