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); asterias: Starry, referring to many small white spots on dorsal (upper) surface of body (See ETYFish).

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).
