if you
learn only 3 things about it ...
It is very rarely seen!
It is carnivorous. Its prey include smaller snails living
beneath the sand.
It
is threatened by over-collection as food and for it shell. |

Where
seen? This magnificent large snail sometimes
seen on our Northern shores and is more common on undisturbed shores.
They are usually found on muddy bottoms, near mangroves and seagrasses.
Features: 15-20cm. Large shell
is beige to orange, sometimes with bands, others without any distinct
markings. The shell is rather thin and quite fragile for such a large
snail. The fleshy body is brown with white stripes, a large foot and
long siphon.
What does it eat? The snail is
a predator and hunts other snails, moving about on the surface. Like
other volutes, it uses its large foot to enclose the prey. It lays
large egg capsules.
Human uses: It is collected for food even, sadly, on Singapore shores.
Elsewhere, the empty shell is used elsewhere to bail
out water from 'sampans' (little boats used by fishermen), also to
measure out sugar, salt and flour in local markets.It
is also called the Indian volute.
"Pearls" may form inside this snail
when something enters the snail's shell and gets covered by shell
material. The "pearl" is not lustrous as it contains no
nacre, but are usually very round and can be as large as a golf ball.
The colours of the "pearl" tend to fade over time so they
are not considered precious gems.
Status
and threats: The Baler volute is listed as 'Endangered'
in the Red List of threatened animals of Singapore due to habitat
loss. Also threatened by indiscriminate fishing with nets. It is also
eaten. Wildfilms had an encounter with a collector who took
one from Changi to eat.
The 1994 Red Data Book of Singapore states "Thought to have been
exterminated from our water, but a recent isolated sighting confirms
their continued presence".
Like other creatures of the intertidal zone, it is affected by human
activities such as reclamation and pollution. Overcollection can also
have an impact on local populations. |
