Cloudy catsharks are small, benthic sharks in the family Scyliorhinidae known for their mottled, cloudy patterning of dark brown or grey patches and spots on a lighter background, providing camouflage against rocky reef and sandy seafloor substrates. Members of this group inhabit shallow to moderate-depth coastal and shelf waters across Indo-Pacific and Atlantic regions, living primarily as nocturnal predators of bottom-dwelling fish, cephalopods, and crustaceans. Catsharks are oviparous, depositing elongated, ridged egg cases often called mermaid's purses attached to coral, algae, or rocky substrate, from which juveniles emerge after weeks to months of development. Several Scyliorhinus species are locally common in their ranges, while others with restricted distributions face pressure from bycatch in commercial fisheries targeting shrimp and demersal fish with bottom trawls, gillnets, and longlines. Catsharks serve as important components of reef and shelf ecosystem food webs as both predators and prey of larger sharks and marine mammals. Most catshark species occupy relatively shallow, accessible habitats where human fishing pressure is greatest.
