Biology     Glossary (e.g. epibenthic)

Found in continental shelf in shallow water to at least 15 m deep. Presumably feeds on small invertebrates and fishes (Ref. 114953). Ovoviviparous (Ref. 50449). Males mature at ca. 32 cm TL, females at ca. 35 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

Preferred temperature (Ref. 123201): 19.8 - 25.9, mean 23.6 °C (based on 13 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00659 - 0.03318), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.2   ±0.7 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):  Low to moderate vulnerability (30 of 100).
