Information
  • Max Size: 20 cm
  • Sea Temperature Range: 24.1-30.3°C
  • Depth: 5-60m
  • Habitat: Coral Reef
  • Habitat Generalisation Index: 6.1
    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).

Rarity
  • Threats: Exploitation, Habitat degradation
  • IUCN Threat Status: Not Evaluated
  • Occurrence: Frequent (14% 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: Large aggregations (144 per transect)
    Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
