Feeds on small to medium-sized bony fishes and occassionally on crustaceans. Viviparous, with 13-26 young in a litter (Ref. 125614). Size at birth measures to about 40-43 cm TL (Ref. 94780). It is taken as bycatch within its range, but is not commercially important (Ref. 125614). Utilized for its fins, meat and liver oil but of little value due to its relatively small size (Ref. 58048).
