Max length : 53.8 cm TL male/unsexed; (Ref. 38391); 44.2 cm TL (female); common length : 42.0 cm TL male/unsexed; (Ref. 114953)
A benthic species found on continental shelf. Produces 2-5 pups during each gestation (up to 12 reported from Argentina). Segregates by sex. Maturity size for males at 23-29 cm TL, females probably smaller (at least in Argentina); birth size at 8-9 cm TL (Ref. 114953).

Estimates based on models
Preferred temperature (Ref. 115969): 7.3 - 14.9, mean 10.4 °C (based on 197 cells).
Phylogenetic diversity index (Ref. 82805): PD50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00464 - 0.02977), b=2.88 (2.66 - 3.10), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100) .
Climate Vulnerability (Ref. 125649): (0 of 100) .
Nutrients (Ref. 124155): Calcium = 35.5 [4.3, 208.5] mg/100g ; Iron = 0.949 [0.183, 3.751] mg/100g ; Protein = 14.7 [10.7, 20.4] % ; Omega3 = 0.317 [0.141, 0.726] g/100g ; Selenium = 20.2 [5.8, 75.4] μg/100g ; VitaminA = 11.6 [2.7, 51.3] μg/100g ; Zinc = 0.717 [0.185, 2.716] mg/100g (wet weight); based on nutrient studies.
