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); fasciatus: Latin for banded, referring to vertical dark bars on body (at least in young). (See ETYFish).

Found on the continental shelf. Newbies are found on beaches of between 1 and 5 m depth, juveniles occupy inshore waters at between 15 and 50 m, and adults are found down to 50 and on upper slopes of up to 250 m in depth (Ref. 56500). Presumably feeds on crustaceans and other benthic invertebrates. Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Size at birth at or below about 39 cm.
