Description

The chain catshark is a small catshark of the family Scyliorhinidae from the western Atlantic. The species grows to about 48 cm and has a slender, yellow-brown body with a conspicuous black chain pattern, to which the name refers. It lives on the outer continental shelf and upper slope over rough, rocky bottoms. Notably this chain pattern shows biofluorescence: under blue light it glows green, possibly for mutual recognition in the deep gloom. As a bottom predator it feeds on small fishes, crustaceans, worms and squid. Reproduction is oviparous. As a small, deep-living shark it is harmless to humans.
