Where
seen? This large snail with an encrusted shell but pearly
inner mouth is sometimes seen on some of our reefy shores. It was previously associated with the Family Trochidae.
Features: 4-6cm. Shell thick heavy, flattened coil with stubby spikes on the outer edge. Upperside usually hidden under a thick layer of encrusting lifeforms. We should not clean off
the camouflaging cover on a living snail as this might put it in danger.
Shell operning pearly and somewhat angular
in outline. Unlike
other commonly seen turban snails, the ooperculum is thin, brown and
made of a horn-like material. Body with dark blotches, a pair
of long tentacles. |
Upper side usuallyunder a thick layer of
encrusting organisms.
