Etymology: Leptocharias: Etymology not explained, perhaps leptos (Gr.), slender; [Car]charias, i.e., a slender shark “very nearly related to Carcharias” (See ETYFish); smithii: In honor of Andrew Smith (1797-1872), Scottish military physician, explorer, ethnologist and zoologist, who collected many South African sharks and coined many of the shark names later used by Müller and Henle (See ETYFish).
Eponymy: Dr Sir Andrew Smith (1797–1872) was a Scotsman who joined the Army Medical Service (1819) after graduating from Edinburgh University. [...] (Ref. 128868), visit book page.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Similar to species of Mustelus but nostrils with anterior flaps formed into distinct barbels (Ref. 5485).
Body shape (shape guide): elongated.
Found on the continental shelf, especially abundant off river mouths on muddy bottoms. Salinity: 35-36 ppt. Oxygen: 3-4 ppm. Feeds on small bottom and littoral organisms like crustaceans, bony fishes, octopi and sponges. Viviparous (Ref. 50449), with 7 young in a litter (Ref. 244). Dental sexual dimorphism is manifested by males having greatly enlarged anterior teeth. Utilized fresh, smoked or dried salted for human consumption, skin for leather.
