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