Habitat and Ecology
Apristurus species are relatively small, sluggish sharks that live on or near the bottom over upper to mid continental and insular slopes. Diet includes crustaceans (penaeid shrimps, euphausids), squids and small fishes. Where known reproduction is oviparous with one egg per oviduct. Egg cases are usually thick-walled, about 5 to 6.8 cm long and 2.5 to 2.9 cm wide. The anterior end of the case has a long weak fibrous thread on each corner. The posterior end usually has two small processes, each with a long coiled tendril. As in shallow water scyliorhinids the coiled tendrils are probably used to attach the egg cases to hard substrates and/or biogenic structures as they are laid.
Recorded at 913 meters.

The smalldorsal cat shark, Apristurus micropterygeus, is a catshark of the family Scyliorhinidae found in the South China Sea, at depths to 915 m. It can grow up to 37 cm. A. micropterygeus is unique among its species in having a narrow and sharply pointed first dorsal fin. However, Nakaya and Sato (2000) recommended that the status of the species be reviewed once additional specimens are available, citing the possibility that the dorsal fin of the holotype may have been malformed. The reproduction of the smalldorsal catshark is oviparous.
