Max Size: 12 cm
Sea Temperature Range: 25.4-33.0°C
Habitat: Coral Reef
Habitat Generalisation Index: 4.8
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). Learn more here
Threats: Exploitation, Habitat degradation
IUCN Threat Status: Least Concern
Occurrence: Widespread (82% 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 (3 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
