Collared carpet sharks are small and bear a slight resemblance to the cat sharks with their cat-like eyes. The mouth, however, is entirely in front of the eyes. The body is cylindrical or slightly depressed and elongated. The origin of the first dorsal fin is behind the bases of the pelvic fins. The biology of these species is only partially understood. They are mainly bottom dwellers and can be found from close inshore to depths of at least 180m. They are found on muddy, sandy or rocky bottom, and are apparently able to change their colors somewhat to match bottom types. It is known that some of the species are oviparous and deposit eggs in elongated, flattened egg cases.
