Oscilla (gastropod)

Oscilla is a genus of very small sea snails, minute marine gastropod mollusks or micromollusks. This genus is currently placed in the subfamily Chrysallidinae of the family Pyramidellidae.

These marine gastropods have shells with intorted protoconchs.

Life history

Little is known about the biology of the members of this genus. As is true of most members of the Pyramidellidae sensu lato, they are likely to be ectoparasites.

Oscilla jocosa may possibly be a parasite on Trochus erithreus (Mienis 2003).
