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
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
