Not all sharks are a dull gray: the coral catshark (Atelomycterus marmoratus), for example, is vibrantly colored. These sharks, which reach more than 2 feet long, live among coral reefs, eating invertebrates and small fish. Their leopard-like pattern provides camouflage as they swim through their reef habitat. Due to habitat destruction and overfishing, the coral catshark is listed as a vulnerable species on the IUCN Red List of Threatened Species.
