snails have an exoskeleton as all other molluscs do, which is what we call a shell. These shells unlike other animal tissues are not made of cells, rather they are composed mostly of calcium carbonate and a little protein.

∙ 9y agoYes they do, some species also give birth to live young. Most snails lay eggs, some in and out of water.
Wiki User
∙ 12y agoNo they are a mollusk not an arthropod and so do not have a cuticle. Their shell is secreted by the mantle.
Wiki User
∙ 12y agoYes. The nematode's exoskeleton is known as a cuticle. The cuticle is both strong and flexible. As the organism grows, it molts the exeskeleton.

Under what conditions is limestone formed?
Many living things, including coral, clams, oysters, and snails, have shells or skeletons made of calcite. When these animals die, their shells pile up a sediment on the ocean floor. Over millions of years, these layers of sediment can grow to a depth of hundreds of meters. Slowly, the pressure of waveringly layers compacts the sediment .Some of the shells dissolve, forming a solution of calcite that seeps into the spaces between the shell fragments. Later, the dissolved material comes out of solution, forming calcite. The calcite cements the shell particles together, forming limestone.
Do snails change shells in the spring?
Snails do not change their shells ever. They keep their shell up to the day they die.

How often does a snail change shells?
Snails don't change their shells. Unlike crustaceans, molluscs like snails keep the same shell throughout their lifetime. The shell is formed from secretions from the snails mantle, the flesh under the shell, and some snails (such as the giant African snails kept as pets) can be seen running their mouths along the edge of their shells, to build up another layer on the shells lip. The stripes that make up the pattern of a snails shell are the result of different compositions of shell material at different times.
How are the snails and slugs different from each other?
