hard substrates within their range (generalists). Learn more here
IUCN Threat Status: Not Evaluated
Occurrence: Common (48% of sites)
Occurrence describes how often the species is found on surveys within its distribution.
It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed
Abundance: Large aggregations (210 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
