Élasmobranches (requins et raies) (sharks and rays) > Carcharhiniformes (Ground sharks) > Triakidae (Houndsharks) > Triakinae
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).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Viviparous with a yolk-sac placenta. Produces 5 to 16 young per litter, with larger adults having larger litters of young. Gestation period is 10 months, birth occurring in April and May. Size at birth about 28 cm (Ref. 244).

Estimates based on models

Preferred temperature (Ref. 123201): 11.1 - 23.2, mean 18.5 °C (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.

Generation time: 5.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth 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.

Nutrients (Ref. 124155): Calcium = 28.8 [8.9, 143.9] mg/100g; Iron = 0.482 [0.142, 1.730] mg/100g; Protein = 20.7 [18.3, 23.0] %; Omega3 = 0.0918 [, ] g/100g; Selenium = 85.5 [25.8, 320.1] μg/100g; VitaminA = 15.1 [5.3, 42.3] μg/100g; Zinc = 1.07 [0.47, 2.18] mg/100g (wet weight);
