How do snails get their shells?

Snails usually begin to grow their protective shells before they hatch.  The common garden snail hatches from a tiny round egg.  Hidden under the young snail’s shell is a flap of skin called the mantle.  The mantle oozes a limy liquid that quickly hardens into a shell.

As the snail grows in size, it adds coil after coil to its shell, building from the open end (for mouth) as fast as it needs more from.  The food that is eaten by the snail provides the materials that form the shell.  Without its shell, a snail would have little protection against drying up.–Dick Rogers

How does a snail move?

Garden Snail

The common snail is slowly inched forward by wavelike motions of its muscular foot.

Almost everyone is familiar with the common garden snail.  Snails are small animals that usually carry their shells on their backs and leave stick trails of goo behind as they creep along.

A snail moves around by creeping on a part of its body that seems to be its stomach.  It is really a broad foot.

The muscles move in a backward, wavelike motion that causes the snail to inch slowly forward.

As the snail moves along, special glands in its foot pour out a slimy fluid that serves as a slippery path to help the snail slide along more easily.

The goo also helps protect the snail’s body as it crawls over sharp twigs and rocks.

As the snail creeps along on its slick pathway, only its head and big foot are out of the shell.

The snail’s eyes are on the tips of its feelers.

To escape dry weather, the snail seals itself inside its shell house with a “door” a dried goo.  – Dick Rogers

 

How does a snail grow its shell?

The shell grows in an ever-widening spiral as the snail continues to add new shell material to its shell during its lifetime.

You’ve probably seen a common garden snail peeking out of its shell as it slowly creeps along on a slick pathway of ooze.

Where did the snail get its shell?  It was born with a tiny shell just the right size for its body.  The shell serves as a suit of armor to protect the snail’s soft body.

As the snail grows, it oozes a slimy shell liquid that hardens into shell, and so the shell grows with the snail. The snail gets its shell-building materials from its food.

There are many kinds of snails, in almost every part of the world.  Some live only on land, some live in lakes and ponds, and others live deep in the ocean. The most snails are hatched from tiny eggs and look very much like their parents when they are born.

Most snail shells are shaped like coiled spirals.  Some are brightly colored with gay stripes.  Some snails grow shells that are no bigger than a pinhead.

But the biggest shells belong to the sea snails called conchs.  Their shell grow to be more than a foot long. – Dick Rogers
