Adults are usually found among large brown algae (Carpophyllum and Cystophora). They feed on weed dwelling crustaceans and small fish (Ref. 9003). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).

Estimates based on models

Preferred temperature (Ref. 115969): 11.9 - 19.6, mean 16 (based on 127 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00372 (0.00145 - 0.00954), b=3.14 (2.91 - 3.37), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.62 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
