Coryphopterus personatusMasked goby
Very difficult to distinguish from C. hyalinus in the field, but apparently best identified by a dusky stripe inside the lower rear margin of the body, dark mask on the face, and a clear patch in the centre of the top of the head.
Max Size: 4 cm
Sea Temperature Range: 26.3-30.4°C
Habitat Generalization Index: 11.52
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).

Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Common (41.7% 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 (872 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
