#3046 - Semicassis paucirugis - Few-wrinkled Bonnet
A medium-sized predatory snail, not often recorded apparently, found along the Western Australian coastline and once? in South Australia.
The Cassidae (which strictly speaking should be Cassididae, and were only promoted to their own family in 2008) are nocturnal sea snails with thick shells that hunt echinoderms. The unlucky prey (usually a sea urchin) is gripped with the foot and bored into with sulphuric acid and a rasping radula.
