A common inshore and offshore shark found on the continental and insular shelves from the intertidal down to at least 100 m. Prefers sandy and gravelly bottom. Feeds primarily on crustaceans (crabs, hermit crabs, lobsters and slipper lobsters). Ovoviviparous (aplacental), with 7 to 15 young per litter. Size at birth about 30 cm. Utilized fresh and dried salted.
Ovoviviparous, embryos feed solely on yolk (Ref. 50449).

Estimates based on models
Preferred temperature (Ref.
115969): 7 - 16.2, mean 10.1 °C (based on 587 cells).
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00200 (0.00164 - 0.00243), b=3.11 (3.06 - 3.16), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.3 se; based on diet studies.
Generation time: 7.5 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilience (Ref.
120179): Very Low, minimum population doubling time more than 14 years (tm=2-3; Fec=7).
Vulnerability (Ref.
59153): High to very high vulnerability (70 of 100) .
