Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Cylichna is a genus of sea snails or bubble snails, marine gastropod molluscs in the family Cylichnidae, the "chalice bubble snails." Snail is a common name for almost all members of the molluscan class Gastropoda that have coiled shells in the adult stage. When the word is used in a general sense, it includes sea snails, land snails and freshwater snails. Otherwise snail-like creatures that lack a shell are called slugs. One species of land snail, the Giant African Snail, can grow to be 15 inches from snout to tail, and weigh 1 kilogram. The largest living species of sea snail is Syrinx aruanus which has a shell that can measure up to 90 cm in length, and the whole animal with the shell can weigh up to 18 kg .
