Peringia ulvae, commonly known as the Laver spire shell or mudsnail, is a European

mollusk in the family Hydrobiidae.[2]

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.

Peringia ulvae is the type species of the genus Peringia.[4]

Distribution

This species occurs on the coasts of the Baltic Sea, the White Sea[5] the eastern Atlantic Ocean and the western Mediterranean Sea,[3] (the Mediterranean records may be in error) [6] including:

  • Great Britain
  • Ireland
  • The Netherlands

The

type locality is "on the shores of Flintshire", Wales, United Kingdom.[1]
The distribution type is Oceanic Wide Temperate

Shells of P. ulvae
The engraving of a shell of Peringia ulvae from its original description (1777) was very small

Description

This species was originally described by Welsh naturalist

type description) reads as follows:[1]

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.

Inhabits Ulva Lactuca on the shores of Flintshire.

"T." is an abbreviated word testa from

Latin language
, that means "shell".

The

last whorl.[3] The shell has 5-7 very weakly convex whorls, that are regularly increasing but not always regularly rounded.[3] The lip is attached to the last whorl.[3]

The width of the shell is 2.5–3 mm.[3] The height of the shell is 4-5.5 mm.[3]

Habitat

A number of individuals of Peringia ulvae on mud

Peringia ulvae is a widespread and abundant member of the

estuaries and salt marshes.[3] It is most common in the upper half of the intertidal zone.[3] It tolerates salinity 1.0-3.3 %.[3]

Peringia ulvae seems to prefer more exposed localities with less vegetation than the mudsnails

Hydrobia neglecta.[3]

Peringia ulvae feeds on

seaweeds directly.[3]

It is pederictional

planktotrophic larvae (veliger)[8] that remain in the plankton for up to four weeks before settlement.[7] This period of development affords the potential for dispersal to new habitats and mixing with geographically separate populations.[7] The species provides an interesting case for molecular analysis as the pelagic dispersal phase raises fascinating questions on gene flow, differentiation, recruitment, and inbreeding, but there remains the potential for self-recruitment of estuarine populations.[7]

One of its natural predators is the Arctic barrel-bubble (Retusa obtusa).[citation needed] In Ireland Peringia ulvae is an important source of food for overwintering waders.
