Laver Spire-shell
Peringia ulvae
Peringia ulvae, commonly known as the Laver spire shell or mudsnail, is a European species of very small aquatic snail with gills and an operculum, a gastropod mollusk in the family Hydrobiidae.
This is arguably a marine snail, but it is often also listed as a non-marine species because it tolerates brackish water and lives in salt marshes and similar habitats.

Description
This species was originally described by Welsh naturalist Thomas Pennant in 1777. Pennant's original text (the type description) reads as follows:
Ulvae. T. with four spires, the first ventricose; of a deep brown color; aperture oval. Size of a grain of wheat. Tab. lxxxvi. fig. 120.

The shell is often heavily corroded, usually whitish with brown peristome present on the last whorl. The shell has 5-7 very weakly convex whorls, that are regularly increasing but not always regularly rounded. The lip is attached to the last whorl. The width of the shell is 2.5–3 mm. The height of the shell is 4-5.5 mm.
