if you
learn only 3 things about it ...
It is among the large snails you might see on our shores.
It is carnivorous. Its prey include smaller snails living
beneath the sand!
Many
volutes are threatened by over-collection as food and
for their shells. |

Where
seen? This large, beautifully marked snail
is sometimes encountered on sandy areas near seagrasses and coral
rubble on some of our shores. It is more commonly seen moving above
the surface at night, and is usually buried during the day.
According to the Singapore Red Data Book, this beautiful snail is
restricted to our part of the world, in particular, Singapore and
Peninsular Malaysia.
Features: 12-20cm. Thick heavy
shell orange, yellow or beige with red or brown zig-zag patterns.
A wide variety of patterns can be seen, although in some, the pattern
may be obscured by encrusting growths. The fleshy body is black with
bright orange or yellow spots. It has a long siphon.
Empty shells of dead noble volutes are quickly taken over by large
hermit crabs.
Baby nobles: Mama
noble volutes lay large egg capsules. Each capsule about 10cm long,
oval with angular bumps, semi-transparent white to beige or yellowish.
The capsules are usually stacked up to form a cylindrical, generally
oval shape and the entire assembly attached to a hard, embedded object
such as coral rubble.
Human uses: Unfortunately, this
beautiful and special animal is collected for food and its attractive
shell.
Status
and threats: The Noble volute is listed as 'Vulnerable'
on the Red List of threatened animals of Singapore due to habitat
loss. It was previously abundant in Singapore but is now considered
vulnerable due to habitat degradation and overcollection for food
and for its attractive shell. Like
other creatures of the intertidal zone, they are affected by human
activities such as reclamation and pollution. Over-collection can
also have an impact on local populations. |
