Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 17 - 19; Rayons mous dorsaux (Total) : 8 - 11; Épines anales: 1; Rayons mous anaux: 16 - 20.
Body shape (shape guide): elongated.
Adults live on reef's surface, often in weedy areas, and on algal-covered rocks or on rubble. They feed on tiny invertebrates and algae (Ref. 13227). 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).
