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).
Eponymy: Dr Waldo LaSalle Schmitt (1887–1977) was an expert on crustaceans who worked at the Smithsonian (1915–1957). [...] (Ref. 128868), visit book page.

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).
