Maturity: L_m ? range ? - ? cm
Max length : 47.0 cm TL male/unsexed; (Ref. 6871)

Found on sand or mud bottoms, occasionally near rocky reefs (Ref. 12951). Feeds on amphipods, shrimp, and worms (Ref. 12951). Produces 1-8 (normally 3) pups during each gestation. Both sexes mature at ca. 20-21 cm TL; born at 9-12 cm TL (Ref. 114953)

Estimates based on models

Preferred temperature (Ref. 123201): 11.7 - 16.6, mean 14.2 °C (based on 82 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01175 (0.00470 - 0.02937), b=2.88 (2.66 - 3.10), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.48 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (37 of 100).
