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); sinusmexicanus: -anus, Latin adjectival suffix that means, when attached to a name, “belonging to”: sinus, Latin for bay or gulf, referring to the Gulf of Mexico, type locality. (See ETYFish).

Marine; pelagic-oceanic; depth range 20 - 250 m (Ref. 55584), usually 42 - 91 m (Ref. 55584). Tropical
Western Central Atlantic: apparently endemic to the Gulf of Mexico, from off Panama City, Florida to the Bay of Campeche.
