Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 16; Mjukstrålar i ryggfenan (totalt) : 11; Taggstrålar i analfenan: 1; Mjukstrålar i analfenan: 18 - 20; Ryggkotor: 35 - 37.
Adults are found in coral reefs at depths of 10 m or shallower (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).
