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);  schmitti: In honor of American biologist Waldo L. Schmitt (1887-1977), curator of marine invertebrates at the U.S. National Museum, who collected holotype. (See ETYFish).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Found on the continental shelf. Feeds on crabs and probably other crustaceans, and presumably small fishes. Ovoviviparous (aplacental) with 2 to 7 pups per litter. Size at birth 26 cm. Utilized for human consumption.

Ovoviviparous, embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace (Ref. 205).
