Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Infrequent (1.1% 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: Many (24 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
