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); higmani: In honor of American fisheries biologist James B. Higman (1922-2009), U.S. Fish and Wildlife Service, for his “initial interest in the species and his care in the preparation of excellent notes on its natural history” while serving as an observer on the vessel from which it was collected. (See ETYFish).

Found on the continental shelf on muddy, sandy and calcareous bottoms. Also occurs in shallow brackish water. Feeds mainly on crustaceans and occasionally on bony fishes, squids, and coelenterates. Viviparous (with yolk-sac placenta), with 1 to 7 young per litter. Catches consisting of mainly adults of one sex suggest at least partial sexual segregation. Utilized for human consumption.
