Etymology: Mustelus: Latin, mustela, -ae = weasel (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal. Subtropical; 45°N - 20°N
Eastern Atlantic: Mediterranean to Western Sahara. Confused with Mustelus mustelus and most data for this species were in part attributable to Mustelus mediterraneus.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 60 - 100 cm
Max length : 190 cm TL male/unsexed; (Ref. ); common length : 120 cm TL male/unsexed; (Ref. )
An inshore, continental bottom-dwelling shark. Probably a crustacean feeder. Presumably viviparous.

Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Probably viviparous (Ref. 244). Distinct pairing with embrace (Ref. 205).

Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 15.3 - 21.6, mean 18.8 (based on 182 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00162 (0.00099 - 0.00265), b=3.11 (2.97 - 3.25), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.8 ±0.4 se; Based on diet studies.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (tm=1.3-2.6(?); Fecundity is presumably low like other Mustelus species).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (54 of 100) .
