Where
seen? Resembling a large stiff white slug, this snail is sometimes seen
in our seagrass meadows and sandy shores at night. When the shell
is seen, it looks like a moon snail that refuses to withdraw into
its shell. It is also called the Ear moon snail or Baby ear moon snail
because of the shape of its delicate shell.
Features: The animal can be 10cm
long. Shell small (about 2cm) thin, white and flat with a wide
shell opening and is usually completely covered by the living animal.
Body leathery and white, huge and unable to retract completely into the shell.
The animal can produce a large amount of slime. |
