Conservation and Rarity
IUCN Status: Least Concern
Occurrence: Infrequent (7.5% 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: Solitary (1 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
