Morphology | Morphometrics
Uncommon and benthic species in rocky habitat (Ref. 34024). Restricted to estuaries, shallow bays and coastal reefs (Ref. 33847). Found on the continental shelf and slope (Ref. 75154). Juveniles are found in seagrass beds in estuaries while adults inhabit caves and rocky recesses (Ref. 33847). Oviparous, with oval pelagic eggs floating in a gelatinous mass (Ref. 205). Important as a recreational fish (Ref. 33839). Minimum depth reported taken from Ref. 57178.

Estimates based on models
Preferred temperature (Ref. 123201
): 14.2 - 18.3, mean 16.4 °C (based on 110 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00275 (0.00131 - 0.00577), b=3.16 (2.98 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.1 ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Very high vulnerability (88 of 100).
