Adults are commonly found in sheltered to moderately exposed areas shallower down to 21 m; less associated with rocky substratum, but may be found under, side or top of rocks. They are found in offshore islands and coastal mainland areas (Ref. 84086). They feed on a range of benthic invertebrates including ophiuroids, archaeogastropods, trichoptera and errant polychaetes (Ref. 84084). 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).

Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00299 - 0.02910), b=3.01 (2.76 - 3.26), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
