Short description Morphology | Morphometrics

Obtuse snout, broader heart shaped disc. Olive to brownish gray above, without definite markings, dorsal and caudal darker than general ground tint, margins of pectoral and pelvic fins paler. Lower surface grayish or yellowish white, posterior corners of pectoral fins and tips of pelvic fins more or less dusky (Ref. 6902).

Biology     Glossary (e.g. epibenthic)

This benthic inshore species is found over soft bottoms to at least 50 m; feeds on benthic crustaceans and polychaetes. Gestation last about a year, produces litters of 1-8 pups in autumn (Ref. 114953). Ovoviviparous (Ref. 50449). Maturity size for males at 43-45 cm TL, females at 42-48 cm TL; birth size at 13-16 cm TL (Ref. 114953).

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

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00308 - 0.01235), b=2.96 (2.77 - 3.15), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100).
Price category (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 35.9 [5.9, 168.6] mg/100g; Iron = 0.87 [0.23, 2.50] mg/100g; Protein = 19.8 [17.6, 21.7] %; Omega3 = 0.372 [0.152, 0.819] g/100g; Selenium = 15.9 [4.6, 44.3] μg/100g; VitaminA = 12.3 [4.4, 32.7] μg/100g; Zinc = 0.667 [0.317, 1.222] mg/100g (wet weight);
