Littorina spp. Periwinkle snails are found in abundance in most Southeastern salt marsh, but they normally co-exist in healthy balance with the marshes' dominant plant, cordgrass (Spartina alternaflora). This snail, like the slugs, has been around for a long time—in the case of the periwinkles they have been on the Maine coast since at least the mid 1800s and we should probably just consider them native. Females lay eggs. - These tiny snails are often mistaken for eggs or rocks. Each year, a single female can lay 10,000 to 100,000 eggs, which hatch into larvae four to seven weeks later. Periwinkle refers to a group of snails belonging to the genus Littorina and includes the following species: the edible periwinkle (L. littorea, L. littoralis), the southern periwinkle (L. angulifera), the smooth periwinkle (L. obtusata), and the gulf periwinkle (L. irrorata). Conservation and Status In its non-native habitat (i.e., the U.S. and Canada), the common periwinkle is thought to have altered the ecosystem by competing with other species, and grazing on green algae, which has caused other algae species to become overabundant. This is another good snail for a cold-water aquarium, as it will constantly clean all surfaces of algae, and also consume any other waste it finds. They occur along the northeastern coast of North America, with a range that begins in Newfoundland and Labrador and ends in New Jersey. The green turban snail, however, showed A decline in population and even with the adaptation seemed to still decline. Periwinkles hosting living polychaetes were considered to be infested.

The mucus helps trap the water stored in their shell from evaporating and drying up in the sun and allows them to stick to the rocks without being pulled out to sea. They are associated with freshwater habitat. The spiral ridges which are marked in young animals tend to become obscured in older individuals, giving the shell a smooth appearance. Periwinkles are widely distributed shore (littoral) snails, chiefly herbivorous, usually found on rocks, stones, or pilings between high- and low-tide marks; a few are found on mud flats, and some tropical forms are found on the prop roots or mangrove trees. Habitat-speciWc size structure variations in periwinkle populations (Littorina littorea) . Recovery following salt marsh restoration in the northern Gulf of Mexico is investigated using meta-analysis for two salt marsh indicator invertebrates, the periwinkle snail (Littoraria irrorata) and amphipod crustaceans (Amphipoda). We investigated the size and density structure of genetically continuous periwinkle populations ( Littorina littorea) on an exposed rocky and a sheltered sedimentary environment on two nearby islands in the south-eastern North Sea (German Bight). The base of the shell is white. The harm from the spill to coastal salt marsh habitat was extensive, and in some instances, permanent. Two dominant organisms commonly found at mid-water levels of the rocky intertidal zone are: goose-necked barnacles and mussels. REFERENCES Bates, T. W. and David W.
