Tropical Indo-Pacific


Translucent greenish colour with 6-7 internal brown bars. Identification is incredibly difficult for most Eviota species, and the name used for the pictured species should be considered a suggestion, rather than a confirmed identity. This may be the same as what RLS divers have labelled Eviota sp. [green], common in NW Australia, but not yet identified. Similar Eviota queenslandica has a pair of black spots on pectoral fin base.


Max Size: 4 cm

Sea Temperature Range: N/A

Depth: 0-65 m.

Habitat Generalization Index: N/A

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: Frequent (18.8% 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.
