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); dorsalis: Latin for “of the back,” referring to “projection of the posterior angle of the first dorsal fin to the vertical of the origin of the ventrals”. (See ETYFish).

Estimates based on models

Preferred temperature (Ref. 115969): 14.8 - 26, mean 16.6 °C (based on 31 cells).

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00234 (0.00106 - 0.00516), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this Genus-BS (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.55 se; based on food items.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Fec=4).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (78 of 100) .
