Same Genus
Distribution
Description
Rare during the day as it buries itself in sand adjacent to reefy areas, although shell fragments are often visible where detritus collects. Emerges partially or fully at night and can be quite common then. Actual shell is quite thinly built. Length to about 50mm. Often covered with mucus and leaves easily visible tracks in the sand.
Information
Max Size: N/A cm

Depth: 0-20m
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: Vulnerable
Occurrence: Common (33.3% 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.
