Scyliorhinidae

Scyliorhinidae is a family of mostly small, bottom-dwelling sharks known as catsharks, found in oceans worldwide. Many species have elongated bodies and distinctive patterns.

Shark: A cartilaginous fish with gill slits and pectoral fins that are not fused to its head. Catsharks belong to the diverse group of fishes commonly called sharks.
Small-spotted catshark: A small northeastern Atlantic catshark with dark spots and a preference for sandy or muddy seabeds. It is a familiar coastal example of the family's bottom-dwelling habits.
Mermaid's purse: A tough, protective egg case produced by some sharks, skates, and chimaeras. Many catsharks lay eggs in these cases, which attach to structures on the seafloor.
Shark egg case: A protective capsule that encloses the developing embryo of an egg-laying shark. Catshark egg cases can reveal reproductive timing and species presence in coastal surveys.
Carcharhiniformes: The largest order of sharks, including catsharks, ground sharks, and hammerheads. This order places Scyliorhinidae among several familiar shark families.
Chain catshark: A western Atlantic catshark marked with a network of dark chainlike bands. Its striking pattern illustrates the varied markings found among catsharks.
Oviparity: A reproductive mode in which embryos develop in eggs laid outside the parent's body. It describes the egg-laying strategy used by many catshark species.
Elasmobranch conservation: The protection and management of sharks, skates, and rays and their habitats. Catshark populations face the same broad pressures affecting other cartilaginous fishes.
Cartilaginous fish: A fish whose skeleton is made primarily of cartilage rather than bone. Catsharks share the defining skeletal material of all sharks and their relatives.
Swollen shark: A western Pacific catshark that can inflate its body by swallowing water or air. Its unusual defensive inflation is a specialized behavior within the family.
