Temperate Australasia


Small species of triton with a spire just more than half the length of the shell and with strong ribs crossed by ridges to give a lattice-like effect over the shell surface. The species is common in cryptic habitats such as under rocks and among encrusting plants and animals. A closely related species, S.eburnea, with finer sculpture and generally a pink top to the spire, is moderately common in Victoria and Tasmania.


Max Size: 3 cm

Sea Temperature Range: 11.2-22.9°C

Depth: 0-15m

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 (5.2% 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 (5 per transect)

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