Eastern Pacific: northern California, USA to the Gulf of California. At the southern part of its range, this species is sympatric with Mustelus lunulatus, but the two are readily distinguishable.

A common inshore and offshore shark found on the continental shelves, and entering shallow muddy bays. Feeds mostly on crabs, including cancrids and grapsids, ghost shrimp, innkeeper (echiuroid) worms (Urechis), and small fish (herring and midshipmen, Porichthys). Viviparous (with a yolk-sac placenta), with 2 to 5 young in a litter. Utilized for human consumption.

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00251 (-0.18994 - 0.19496), b=3.17 (3.07 - 3.27), based on LWR estimates for this genus-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.5 ±0.5 se; Based on diet studies.

Resilience (Ref. 69278): Very Low, minimum population doubling time more than 14 years (K=0.22-0.35; tm=1.3-2.1; tmax=12; Fec=2).

Vulnerability (Ref. 59153): Moderate to high vulnerability (55 of 100) .

Price category (Ref. 80766): Medium.
