Conservation and Rarity

IUCN Status: Least Concern

Occurrence: Frequent (11.6% 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 (11 per transect)

Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
