Where
seen? Only the empty shells of these snails have been seen
washed up on our shores. It is considered uncommon and usually found
in deep water.
Features: 8-10cm in diameter. Shell
flat coiled with 14 long spines on the last outer whorl.
Underside with fine spiraling lines. Objects are rarely attached to
the shell, except on early whorls.
The Family Xenophoridae are called carrier shell snails because they
cement bits of shells of other snails and clams onto their own shell.
The living snail has a very long proboscis which it uses to attach
these bits to its own shell. See a photo
of a snail doing this.
Sometimes confused with turban
snails (Family Turbinidae). Unlike turban snails, carrier shell
snails do not have shiny mother-of pearl on the inside of the shell.
Human uses: Occasionally collected
in shrimp trawls. The shell is used in shellcraft. |
