Common on the continental shelf-slope break. Inhabits deep waters where inidividuals are usually in deeper waters at the southern edge of distribution. Reported to feed on invertebrates (euphausiids, polychaetes, amphipods, crabs, and mysids). Size at maturity for males 44 cm TL and 45 cm TL for females, where males grow to 62 cm TL and females to 58 cm TL; size at birth is 12-16 cm TL. Estimated maximum age for females 17 years and for males 18 years, Egg cases are very small (5.0-6.6 cm TL), colour light to dark brown, with dorsal surface covered with fine fibers, while ventral with either a thin fibrous layer or without.
