Where
seen? Only the empty shells have been
seen on our shores so far. The living animal has yet to be encountered
on the intertidal. The empty shells seen are usually occupied by a
hermit crab. Elsewhere, they are found on soft bottoms.
Features: Those seen 5-7cm, can
grow to 15-17cm long. Elegant shell with regular spirals which are
finely ridged. It is herbivorous and lives on sandy and muddy areas
of the intertidal zone. |
