Otherwise snail-like creatures that lack a shell (or have only a very small one) are called slugs. Nothing is known about the biology of the members of this genus. This genus is currently placed in the subfamily Chrysallidinae of the family Odostomiidae. Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Prestoniella is a small genus of very small sea snails, pyramidellid gastropod mollusks or micromollusks. The original description by Laseron (1958) (in French) is extremely short and only states that the base of the shell is without spiral ribs. 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. As is true of most members of the Pyramidellidae sensu lato, they are most likely to be ectoparasites.
