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).

Description synthétique Clés d'identification | Morphologie | Morphométrie

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.

Estimates based on models

Preferred temperature (Ref. 115969): 19.2 - 28, mean 26 (based on 116 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.8 ±0.49 se; based on food items.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (Fec=7).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (53 of 100).
