The Chain Catshark is generally a bottom-feeder since it is known to live on the bottom of the ocean floor. In 1998, a study was done to determine what types of food Chain Catsharks typically eat. Scientists who performed the study conducted a “gut content analysis,” which involved cutting open Catshark stomachs to see what was recently eaten by the sharks.

Scientists examined the stomachs of 81 Chain Catsharks, and in the stomachs, the found squid, bony fish, marine works (such as the lugworm or clam worm), and crustaceans, including lobster, shrimp and crabs.

While this study was limited, it gives a good idea of the Chain Catshark Diet.
