Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 15 - 19; Radios blandos dorsales (total) : 9 - 11; Espinas anales: 1; Radios blandos anales: 18 - 22; Vértebra: 37 - 40.
Body shape (shape guide): elongated.
Adults are found in rocky shore areas and rocky surge channels with sparse coral growth at depths of less than a meter to 6 m (Ref. 9849). 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).
