Occurs close inshore and offshore down to at least 100 m depth. Presumably feeds on small fishes, cephalopods and crustaceans. Ovoviviparous, with 8 to 22 young in a litter. Size at birth about 20 to 21 cm. Utilized for human consumption.

Estimates based on models
Preferred temperature (Ref. 115969): 9.7 - 27, mean 20.2 (based on 252 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00180 - 0.01010), b=3.04 (2.84 - 3.24), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 4.4 ±0.4 se; based on diet studies.
Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Fec=8).
Fishing Vulnerability (Ref. 59153): High to very high vulnerability (72 of 100).
