Snail Facts
Did you know that a snail only has one foot.
Did you know that a snail can slide over a razor
blade without being hurt!
Snails
are GASTROPODS. Gastropod means " Belly footed animal." Snails
are just a part of as many as 50000 kinds of species of mollusc
that
live on land and sea.
Snails have prominent tentacles.The tentacles are
like two hollow stalks.In many species the eyes are located on
these tentacles.
Muscles in the snail's body can pull the eyes down the hollow
stalks and into the body for protection.
Snails hibernate in the winter.This means they
go to sleep while the weather is very cold. Snails bury themselves
and close up the entrance to their shell with a door of slime.
This hardens into a tough skin. This tough skin keeps predators
out
but a tiny hole allows air in.
Some snails that live in the desert have been known to remain
in their shells for two or three years.
Snails live for about five years.
When they are
about three years old they lay eggs. Snail eggs are round and
very small. You can find them in clusters of about thirty under
stones.
Most snails are hermaphrodites.This means they can fertilize
their own eggs.
Some snails are poisonous and their poison can
be fatal to humans. The venom paralyses their prey.
These snails are known as Cones and are marine
molluscs. Cones live in sandy mud mainly in the tropics and are
found on the
reefs of Australasia. Cones are very large and their shells are
valued by collectors.
They have few predators.
In Britain it has been observed that thrushes leave yellow-banded
snails alone, leading scientists to believe they could be poisonous.
