Short description
Identification keys | Morphology | Morphometrics
Adults inhabit shallow coastal to outer reef crests and slopes but reported to 30 m depth (Ref. 48636). Also found in high isolated tidal pools and wave-swept tops of lagoon reefs (Ref. 1602). Occasionally found in intertidal pools. 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). Minimum depth of 0 m reported from Ref. 90102.
