Sassia verrucosa
Verrucose triton
Same Genus
Distribution
Temperate Australasia
Description
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.

Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Infrequent (5.3% 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: Few (4 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
