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); punctulatus: Diminutive of punctum (L.), spot, i.e., having tiny spots, referring to small black spots often present on body. (See ETYFish).

Estimates based on models
Preferred temperature (Ref.
123201): 15.3 - 21.6, mean 18.8 °C (based on 182 cells).
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00219 - 0.00549), b=3.16 (3.03 - 3.29), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.8 ±0.4 se; based on diet studies.
Generation time: 3.3 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Weerstandsvermogen (Ref.
120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (tm=1.3-2.6(?); Fecundity is presumably low like other Mustelus species).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (51 of 100).
Nutrients (Ref.
124155): Calcium = 15.9 [4.3, 80.9] mg/100g; Iron = 0.485 [0.153, 1.866] mg/100g; Protein = 22.1 [19.7, 24.4] %; Omega3 = 0.144 [0.057, 0.357] g/100g; Selenium = 54.4 [14.4, 196.5] μg/100g; VitaminA = 3.8 [1.2, 12.1] μg/100g; Zinc = 0.461 [0.202, 0.945] mg/100g (wet weight);
