Épines dorsales (Total) : 15 - 19; Rayons mous dorsaux (Total) : 8 - 11; Épines anales: 1; Rayons mous anaux: 16 - 20; Vertèbres: 36 - 37.
Adults are found at depths of 8 m and shallower, in surge channels and exposed rocky and coralline boulders (Ref. 90102). 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).
