Biology     Glossary (e.g. epibenthic)

Found on the continental shelves and upper slopes from inshore to deeper waters. Prefers rocky, algal-covered areas of kelp beds. Nocturnal. Feeds on bony fishes, alive and dead, and probably crustaceans. Can inflate its stomach with water or air. Oviparous. Can live in tanks for several years and females can lay eggs in captivity. Occurs in aggregations while resting, sometimes piled one on top of the other. Sometimes caught by sport divers but not used.

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

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 123201): 14.8 - 28.1, mean 22.3 °C (based on 90 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00263 (0.00139 - 0.00497), b=3.21 (3.04 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.61 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (66 of 100).
