Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 180 cm WD male/unsexed; (Ref. 2850); common length : 100.0 cm WD male/unsexed; (Ref. 9257); max. published weight: 82.1 kg (Ref. 40637)

Commonly found in sandy and muddy bays and sloughs, also on rocky bottom and in kelp beds (Ref. 2850). Sometimes buries itself in sand (Ref. 2850). Found singly or in schools (Ref. 12951). Feeds on bivalves, snails, polychaetes, shrimps, and crabs (Ref. 9257). Ovoviviparous (Ref. 50449). Venomous spine on tail. Not fished commercially, but shows up as by-catch species (Ref. 9257).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 115969): 12.4 - 23, mean 20.6 (based on 34 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00123 - 0.01235), b=3.08 (2.82 - 3.34), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.1 se; based on diet studies.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (tm=3; tmax=23; k=0.09-0.22).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (75 of 100).
