Biología     Glosario (por ej. epibenthic)

A benthopelagic species found inshore over sandy bottoms from nearshore to about 20 m depth. Feeds mainly on molluscs (Ref. 114953). Ovoviviparous (Ref. 50449). Pups 38-48 cm disc width at birth (Ref. 114953).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00461 - 0.02857), b=2.98 (2.76 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec assumed to be <100).
Vulnerability (Ref. 59153):  High to very high vulnerability (68 of 100) .
Price category (Ref. 80766):   Medium.
