Aquarium snails are different from regular land snails. All aquatic snails have gills. Just like their land relatives, these snails also have radula(rasping tongue),tentacles, and hard shells. Aquatic snails do not have as developed eyes as land snails. Many aquatic snails have a door or an opcerium at the entrance of their shell. Some aquatic snails also grow to the size of a baseball.
Snails dont rebuild their shells. I used to think that slugs were just snails without shells, but without their shells, snails die. Their bodies are sort of connected to the shells.
Snails, which are members of the Mollusk family, are found both on land and in the water. Most wear a protective shell, made of calcium, that is produced by the snail and grows as the wearer grows in size. Some snails, such as land slugs, do not have shells.
