Localised, Temperate Australasia


White body and mantle covered in orange spots with lines around the rims of the rhinophores and gill cavities. The size and number of the spots is highly variable and appears to vary with location. This nudibranch lives in a similar habitat to Chromodoris epicuria but is slightly less common.


Max Size: N/A cm

Sea Temperature Range: N/A

Depth: 0-30m

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: Infrequent (7.5% 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.
