Elasmobranchii (sharks and rays) > Carcharhiniformes (Ground sharks) > Leptochariidae (Barbeled houndsharks)
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).

Max length : 77.0 cm TL male/unsexed; (Ref. 244); 82.0 cm TL (female); common length : 55.0 cm TL male/unsexed; (Ref. 26999)

Short description Morphology | Morphometrics

Similar to species of Mustelus but nostrils with anterior flaps formed into distinct barbels (Ref. 5485).

Biology     Glossary (e.g. epibenthic)

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.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Viviparous, placental (Ref. 50449), with 7 young in a litter (Ref. 244). Distinct pairing with embrace (Ref. 205).
