It is a very small species with a shell height of less than 2 mm (0.08 in) and a shell width of around 1 mm (0.04 in). Z. tholussum individuals are completely blind and possess translucent shells with five to six whorls. <br /><br /><br />3) Conus is a large genus of small to large predatory sea snails, marine gastropod molluscs, with the common names of cone snails, cone shells or cones. This genus is placed in the subfamily Coninae within the family Conidae. Geologically speaking, the genus is known from the Eocene to the Recent (Holocene) periods. Conus species have shells that are shaped more or less like geometric cones. Many species have colorful patterning on the shell surface. Conus snails are mostly tropical in distribution.<br /><br />4) Hinea brasiliana is a species of small sea snail in the family Planaxidae. It is one of only a few sea snail species able to bioluminesce.<br /><br />5) Murex is a genus of medium to large sized predatory tropical sea snails. These are carnivorous marine gastropod molluscs in the family Muricidae, commonly called "murexes" or "rock snails".<br /><br />6) Achatina achatina, common name the giant Ghana snail, also known as the giant tiger land snail, is a species of very large, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Achatinidae. The name 'Achatina' is from 'achates', Greek for agate.<br /><br />7) Ampullariidae, common name the apple snails, is a family of large freshwater snails, aquatic gastropod mollusks with a gill and an operculum. This family is in the superfamily Ampullarioidea and is the type family of that superfamily.<br /><br />Snail is a common name that is applied most often to land snails, terrestrial pulmonate gastropod molluscs. However, the common name "snail" is also applied to most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also thousands of species of sea snails and freshwater snails. Occasionally a few other molluscs that are not actually gastropods, such as the Monoplacophora, which superficially resemble small limpets, may also informally be referred to as "snails".<br /><br />Snail-like animals that naturally lack a shell, or have only an internal shell, are usually called slugs, and land snails that have only a very small shell (that they cannot retract into) are often called semislugs.<br /><br />Snails that respire using a lung belong to the group Pulmonata, while those with gills form a polyphyletic group; in other words, snails with gills form a number of taxonomic groups that are not necessarily more closely related to each other than they are related to some other groups. Both snails that have lungs and snails that have gills have diversified so widely over geological time that a few species with gills can be found on land and numerous species with lungs can be found in freshwater. Even a few marine species have lungs.<br /><br />Source:<br />http://en.wikipedia.org/wiki/Snail
