Snails do not receive a new shell after they lose one, or better yet do not usually lose their shell. Every year as a snail grows bigger it adds new rings to its shell. These rings are clearly visible from year to year and often have different shades.
i think that they dont
no. all snails young and old have a shell at all times even if they switch shells. a slug is another type of animal that doesn't have a shell.
Periwinkles will out grow their shells, another creature will then take that shell and the periwinkle will take another old shell. This is an example of symbiosis. :)
you can check their ages by counting the cracks on its shell. he he The bigger the snail is the older it is, also as snails age they move slower. Cracks on snails shell happen natrually, if they are dropped or something heavy is dropped on them, a crack can form. A young snail might have more cracks then a very old snail.

They dont grow them, they find them. When they are born, they have to find a small enough shell for them that is comfortable to wear. As snails get older and grow bigger, they have to find a new, bigger shell because they outgrew their old one.
What a thoughtful question! Snails are hatched from eggs. When they hatch, they eat most of the shell, but a small part of it stays with them and that is the beginning of their shell. As the snail grows, so does its shell -- in a spiral shape. New shell is added at the opening of the shell. In the center of the spiral is the part of the shell that the snail began life with. The shell is made from several layers. The thin outer layer is made from an organic substance known as conchiolin. The thicker layer underneath is formed from three layers of crystalline calcium carbonate, similar to the chicken egg of which you may be more familiar. The color of the shell depends on the types of food the snail is eating and also the type of snail. Snails can live live from 5-10 years. I thought that was pretty amazing! The oldest snail known lived to be 15 years old. Snails are usually considered to be pests. But snails are also very beautiful and fun to watch. Slugs are shell-less snails and eat plants as well. To tell the difference between a slug and a snail track, look to see if the slime trail is a continuous trail; if so, then it is slug. If the trail has breaks in it, it's a snail.
Get a new one!
An old coconut shell cup.
it is normal for turtles to lose pieces from the bottom of their shell. i have a 3 year old long neck turtle of my own and he had a brown tummy and now it is white. this is due to the growth of the turtle.
depends on the mollusk or shell fish giant clams have been found that are over a hundred years old is a sea turtle a shell fish,or mollusk these are regularly found to be over 100 years old
Older eggs lose weight because the egg whites evaporate through the shell. also The loss of moisture through the shell of the egg as they age causes an air bubble in the end of the egg, which is why old eggs float when immersed in a bowl of water.
Because he doesn't fit his old shell (too small) and he needs a new shell.
