One of the largest gastropods living in temperate Australian waters, and so can usually be easily recognised by its size as well as by its reddish brown colour.


Max Size: 20 cm

Sea Temperature Range: 15.3-23.2°C

Depth: 0-40m

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 (15.4% 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: Solitary (1 per transect)

Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
