• IUCN Threat Status: Least Concern
• Occurrence: Widespread (60% 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: Few (4 per transect)
  Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
