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); mosis: Etymology not explained (no written description); since mosis is the Latin spelling of Moses, possibly an allusion to this shark’s type locality in the Red Sea (See ETYFish).

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Spine anali: 0. A smoothhound without spots and often with a white-tipped 1st dorsal fin; adults with a hard, bone-like growth embedded in snout, readily felt by pinching it (Ref. 5578). Grey or grey-brown dorsally, white ventrally (Ref. 5578). Pectoral fins with pale trailing edges (Ref. 5485).
Body shape (shape guide): elongated.
Occurs in continental waters, both inshore and offshore (Ref. 244). Sometimes seen on coral reefs (Ref. 244). Feeds on small bottom fishes, mollusks, and crustaceans (Ref. 244). In the Gulf of Aqaba on cephalopods, decapods and terrestrial food items while off Al-Ghardaqar near the entrance of the Gulf of Suez, prawns, small crabs and small fish were found in the specimens (Ref. 124465). Viviparous (Ref. 244). Caught by shore anglers (Ref. 5578). Readily lives in captivity (Ref. 244). Utilized as a foodfish (Ref. 244).
Viviparous, with 6 to 10 young in a litter; born at 26-28 cm (Ref. 5485). Distinct pairing with embrace (Ref. 205).
