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); griseus: Medieval Latin for gray, referring to gray or gray-brown color. (See ETYFish).

An inshore bottom-dwelling shark found down to at least 51 m (Ref. 244); also dwells in semi-enclosed sea areas with sand bottom (Ref. 11230). Probably feeds on benthic invertebrates, especially crustaceans (Ref. 13563). Viviparous, with a yolk-sac placenta (Ref. 244).

Estimates based on models

Preferred temperature (Ref. 115969): 11.1 - 23.2, mean 18.5 (based on 212 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00224 (0.00105 - 0.00478), b=3.14 (2.97 - 3.31), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.5 ±0.4 se; based on diet studies.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (tm=5.3-6.5; tmax=9; Fec=5).

Fishing Vulnerability (Ref. 59153): High vulnerability (59 of 100).

Catégorie de prix (Ref. 80766): Medium.
