• Max Size: 32 cm
• Sea Temperature Range: 22.3-31.2°C

• Habitat: Coral Reef
• Habitat Generalisation Index: 16.5
  Also referred to as the SGI (Species generalisation index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

• IUCN Threat Status: Least Concern
• Occurrence: Frequent (17% 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.
