Etymology: Mustelus: Latin for weasel, an ancient name for sharks, possibly referring to the pointed snouts, swift movements and/or rapacious feeding behavior of smaller predatory sharks [strictly not tautonymous with Squalus mustelus Linnaeus 1758 since type was designated by the ICZN] (See ETYFish); californicus: -icus (L.), belonging to: California, referring to its common occurrence along the coast of California (USA) (See ETYFish).

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.
Viviparous with a yolk-sac placenta (Ref. 244).
