Found on the continental shelf and upper slope from the intertidal region to deeper waters over sand and gravel bottoms (Ref. 244). Feeds on crustaceans, octopi, bony fish, and fish offal (Ref. 5578). Ovoviviparous (Ref. 50449).

Bayesian length-weight: a=0.00224 (0.00109 - 0.00459), b=3.18 (3.01 - 3.35), based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±0.5 se; Based on diet studies.
Resilience (Ref. 69278
