Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 16 - 18; Rayons mous dorsaux (Total) : 10 - 12; Épines anales: 1; Rayons mous anaux: 19 - 21. Males are dark-headed (Ref. 37816).
Adults inhabit surge-swept reef margins (Ref. 1602). Found on rock surfaces under ledges (Ref. 13227) of coral reefs covered with algae (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).
