Max Size: 40 cm
Sea Temperature Range: 20.2-32.2°C
Habitat: Coral Reef, Soft sediment
Habitat Generalisation Index: 15.6
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: Frequent (13% 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.
