Elasmobranchii (sharks and rays) > Carcharhiniformes
(Ground sharks) > Leptochariidae
Etymology: Leptocharias: Greek, leptos = thin + Greek, leptos = thin + Greek, charax, -akos = a marine fish without identification (Ref. 45335). More on authors: Müller & Henle.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; demersal; depth range 10 - 75 m (Ref. 244), usually 10 - 60 m (Ref. 5377). Tropical; 20°C - 27°C; 22°N - 23°S, 26°W - 17°E

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
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)
Similar to species of Mustelus but nostrils with anterior flaps formed into distinct barbels (Ref. 5485).
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.
