Morphology | Morphometrics
Adults inhabit lagoons and seaward reefs (Ref. 90102). They are found in caves, crevices and on flat surfaces of coral, sponges or rubble with algae (Ref. 48636). Some live on live corals (Ref. 94101). 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).
