Biology     Glossary (e.g. epibenthic)

The largest species of the family (Ref. 5319). Primarily an offshore species that prefers rocky or muddy banks. Feeds during the day on small, bottom-dwelling invertebrates. Occasionally also on squid and small fish. Also caught by artisanal and game fisheries (Ref. 9492).

Estimates based on models

Preferred temperature (Ref. 123201): 15.4 - 23.9, mean 18.1 °C (based on 40 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01820 (0.00738 - 0.04487), b=2.99 (2.77 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.3 se; based on diet studies.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
Price category (Ref. 80766):   Unknown.
