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); schmitti: In honor of American biologist Waldo L. Schmitt (1887-1977), curator of marine invertebrates at the U.S. National Museum, who collected holotype. (See ETYFish).

Estimates based on models

Preferred temperature (Ref. 115969): 4.5 - 14.2, mean 7.9 (based on 118 cells).

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

Bayesian length-weight: a=0.00257 (0.00165 - 0.00399), b=3.10 (2.97 - 3.23), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.6 ±0.3 se; based on diet studies.

Resiliência (Ref. 120179): Muito baixo, tempo mínimo de duplicação da população maior que 14 anos (Fec=2-3).

Fishing Vulnerability (Ref. 59153): High vulnerability (58 of 100).

Climate Vulnerability (Ref. 125649): Very high vulnerability (87 of 100).

Categoria de preço (Ref. 80766): Medium.
