Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 16 - 18; Raggi dorsali molli (totale) : 10 - 12; Spine anali: 1; Raggi anali molli: 19 - 21. Males are dark-headed (Ref. 37816).
Body shape (shape guide): elongated; Cross section: oval.
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).
