Assiminea is a genus of minute, salt-tolerant snails with an operculum, aquatic gastropod mollusks, or micromollusks, in the family Assimineidae.^[1]

Distribution and habitat[]

These snails can be found worldwide. They live usually in brackish water and salt marshes of tropical and temperate regions, at beaches, in water and at land.

Description[]

These are very small to medium large snails, between 2 and 13 mm). Some adults do not exceed a size of 3 mm. The shape of the thin shells is somewhat ovately conical. The margin of the aperture is simple. The operculum is in most cases horny.^[2][3] The eyes are at the end of short, stout stalks. They feed on vegetable detritus and small algae. They lay their eggs in the mud, and hatch as free-swimming larvae.
