All About Snails

Characteristics of Snails

Yes, the eye is on the tip of the tentacle or at the base of the tentacle for marine species. The snail has two pairs of tentacles on its head. One pair is longer than the other pair. The eyes are on the longer pair. The shorter pair is used for smelling and feeling its way around. The tentacles are very important to the snail.

A snail have something called a radula in its mouth for grinding up its food. This radula is like a rough tongue, something like a file with rows of tiny teeth which it uses to scrap off leaves and flowers to eat. Many people get upset and farmers get angry when snails eat their plants and crops. Snails can cause serious damage to crops. Snails eat mostly living plants as well as decaying plants. They also chew on fruits and young succulent plant barks.

How big can the snail grow?

The snail moves by creeping on a flat "foot" underneath the body. The band of muscles in the foot contract and expand and this create a kind of rippling movement that pushes the snail forward. The "foot" has a special gland that produces a slimy mucus to make a slippery track. You can often see these silvery tracks in the garden. The slime comes out from the front and hardens when it comes into contact with air. The snail is able to move on very sharp pointed needles, knife, razors and vines without being injured because the mucus-like secretion helps to protect its body.

Look at how the snail wraps its soft body around the branch so that it will not fall off.

The snail is both male and female. Therefore, it can produce sperms and eggs at the same time ! Isn't that incredible ? However, to fertilize the eggs, the snails need to exchange sperms with each other. An animal which is both a male and a female is called a hermaphrodite. The brown garden snail lays about 80 spherical shaped white or yellowish colored eggs at a time into the topsoil of the ground. It can lay eggs up to six times a year. Snails take about 2 years to become adults.

Life History of the snail

Snails spend many hours courting before they mate. They twist themselves around each other and cover themselves in frothy slime. After mating, each snail will go search for a soft ground to dig and lay its eggs. The snail lay its eggs in a nest, 2.5 to 4 cm deep in the soil. Each snail can lay an average of 85 eggs and they hatch in 2 to 4 weeks, depending on the temperature and moisture of the soil. The eggs are concealed with a mixture of soil and mucus. They are then covered with excrement. Low temperatures of less than 12C and low humidity inhibits laying eggs. Snails lay eggs most often during the warm and damp weather. It can be as often as once a month or every 6 weeks. Their most active months are from February to October.

The first thing that a newly hatched snail does is to find food. It will eat whatever that is left of its eggshell too. It will also eat any eggs that have not hatched yet. As the snail grows, its shell grows too in a spiral shape. The new shell is added at the opening of the shell. The part of the shell the baby snail was born with, ends up in the middle of the spiral.

The snails have enemies too

Snails have many natural enemies. They are the ground beetles, snakes, toads, turtles, and birds including chickens, ducks and geese.

POND SNAILS

It is fun to play in the country. If you come across a pond in the country, you will find animals like fish, prawns, insects and the pond snail. The pond snail is, in many ways like the garden snail. Pond snails are usually tan or dark brown in color.

How do they breathe in water?

Some pond snails have gills to breathe in water. Those with gills will live at the bottom of the pond. Those that do not have gills, will come up to the surface to breathe. These snails will live on the surface so that they can come up to breathe easily.

Do you know that pond snails can be eaten?

One important thing to remember here is to make sure that you clean and rinse the pond snails with plenty of clean water to wash away the dirt and mud.

What does the pond snail feed on?

The pond snail feeds mainly on plants like algae and microscopic creatures that are found on the surface of water weeds. They eat by scraping bits off with their rough tongue just like the garden snails.

How does the pond snail reproduce?

The pond snail reproduces just like the garden snail. It is a hermaphrodite. The only difference is that, unlike the garden snail, the pond snail carries its fertilized eggs with it. The baby snail will only leave its mother when it is hatched.

How to collect pond snails?

First of all, you will need a spade, fishing net, a container (to put your snails in). Make sure your container is not air tight so that the snails can breathe. You can do this by making tiny holes on the lid. You need a lid to cover your container because snails can crawl on any texture or surface. Choose a damp spot near the pond and then use your spade to loosen the ground and you will find many snails just beneath the surface.
