Conical slipper snail
Desmaulus extinctorium
Family Calyptraeidae
updated Oct 2016

Where seen? This snail is often seen on the inside of a shell occupied by a hermit crab. But it is usually overlooked as attention is focused on the more animated hermit crab. It was previously known as Calyptraea extinctorium.

Features: 1-2cm. The shell is thin, usually forming a pointed conical shape. May be white, pinkish or even reddish, with fine lines.

Sometimes confused with limpets which are also gastropods but which can move about. Here's more on how to tell apart limpets, slipper snails and similar animals.
