• Habitat Generalisation Index: 22.4
  Also referred to as the SGI (Species generalisation index), this describes the habitat niche breadth of the species.

• IUCN Threat Status: Least Concern
• Occurrence: Common (24% 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 (2 per transect)
  Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
