Snails are animals which belong to the group called mollusks.
The most widespread snail in the world is Helix Pomatia. Snail live on the ground,
but some species of them live in the water. Also there are some snails which
are poisonous, such as the marbled cone snail. They are known for their calcium
carbonate shell which helps it protect itself from the sun and enemies. All of
their vital organs are placed in the shell, while their lower part is called a foot
because they use it for moving.
Some snail do not have shell. The land snails are
hermaphrodite and they eat grass to survive. However, just because they are
hermaphrodite it does not mean they don’t mate. In the process of mating they
exchange semen which can be used over a period of few years when necessary.
Snails that live in cooler environments hibernate during the
winter.
When we are talking about snails, we always wonder why they
move so slowly. However, compared to their body dimension, the animal isn’t as
slow as we think. The normal sped of a garden snails is 0.03 mph. Evolution
made snails slow. Snails still evolve and they are getting much slower.
The reason? They are reducing their metabolism and together
with it they move more slowly. Their energy is used for faster growth and better
reproduction instead of speed.
