About the chain catshark!

The chain catshark is a type of ground shark that is biofluorescent, meaning it uses natural luminescence to attract others of its kind. The chain shark is light grey in color, like most sharks, but has a dark greyish black pattern across its body that resembles a chain link fence pattern. This patterning helps the shark to camouflage when it is resting on the bottom of the ocean amongst rubble and rocks, and the chain pattern also mimics reflective shapes made by light through the water. Chain catsharks live within western Central Atlantic and the northwest Atlantic Ocean, and can grow to be about two feet in length.
