Maturity: L_m ?, range 70 - 74 cm
Max length : 87.0 cm TL male/unsexed; (Ref. 244); 101.0 cm TL (female); max. reported age: 9 years (Ref. 6983)

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 Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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. 115969): 11.1 - 23.2, mean 18.5 °C (based on 212 cells).

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

Bayesian length-weight: a=0.00240 (0.00106 - 0.00541), b=3.13 (2.95 - 3.31), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.4 se; based on diet studies.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (tm=5.3-6.5; tmax=9; Fec=5).

Vulnerability (Ref. 59153): High vulnerability (63 of 100) .

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 41.6 [7.7, 167.9] mg/100g ; Iron = 0.372 [0.126, 1.463] mg/100g ; Protein = 20.4 [18.0, 22.5] % ; Omega3 = 0.0905 [, ] g/100g ; Selenium = 72.6 [20.7, 269.9] μg/100g ; VitaminA = 16.5 [6.2, 45.0] μg/100g ; Zinc = 0.86 [0.38, 1.95] mg/100g (wet weight);
