Unlike the related periwinkle, L. littorea, it is native to the coastline at our study site in Nahant, Massachusetts. & Zhou Mingjiang, 1986. , Littorina littorea can be highly variable in phenotype, with several different morphs known. The species is typically intertidal and in ideal conditions may be found up to the high tide level. The eggs and larvae form the main mode of dispersal. It is also tolerant of brackish water. 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). Habitat: Intertidal zones, rocky shores, tide pools, pilings, and rock jetties. It is also tolerant of brackish water. Color: Shell is dark in color, usually brown, black, or gray. A Practical Guide. Increases in water flow rates above 6 knots may cause snails in less protected locations (e.g. Lancashire Environment Record Network, 2018. Decreases in flow rate are not likely to have any effect. Females seem to grow more rapidly than males, and in specimens above 25 mm in height, females seem to dominate. Littorina littorea feeds on diatoms, Enteromorpha, Ulva and Porphyra.

St Andrews BioBlitz 2014. It uses its radula to scrape algae from rocks and, in the salt marsh community, pick up algae from cord grass or from the biofilm that covers the surface of mud in estuaries or bays. Abundances of periwinkles (213±114 m–2) and barnacles abruptly de-creased in the adjacent shallow subtidal zone, which served as a habitat for older snails (>13 mm).L. The method used for grading differs, but two proven methods include a Trommel screen with horizontal bars instead of a mesh, and a circle-throw vibrating machine also using bars. Littorina littorea (Common Periwinkle) is too rare in the Chesapeake region to have any economic importance. Global map of species distribution using gridded data.

By Colin Little, J. & Beckwith, P., 1999. Fish, J.D. Volume 53, Issue 2. The species is small and the shell is quite thick, particularly in older individuals. Higher nutrient levels may benefit the algal substrata and food used by the snail. Littorina littorea (Linnaeus, 1758). Generally black or dark grey-brown in colour, often lighter towards apex, with dark spiral lines.  Strandsnegler (Littorina) er en slekt med små marine snegler.Det norske navnet strandsnegler brukes også om hele familiegruppen strandsnegler.De lever i og like under tidevannssonen på berg og klipper. Erlandsson, J.  This species is also found on the west coast of the United States, from Washington to California. The common periwinkle snail is believed to have been an important source of food in Scotland since at least 7,500 BCE. Also commonly known as the 'edible periwinkle'.  The NBN Gateway - Littorina littorea has a distribution map over the UK and Ireland. To conduct the study of Littorina littorea, 199 individuals were collected: 61 - in the Porya bay and 138 - in the island of Ryashkov. & Picton, B.E., 1997. Littorina littorea. , A study in Plymouth Sound suggests an initial growth reaching up to 14 mm in height December the first year, and 17.4 mm by the end of the second year.

The species is widespread and often common or abundant. Merseyside BioBank (unverified). TWIC Biodiversity Field Trip Data (1995-present). Littorina littorea is a mollusc which is often distributed on rocky coasts, from the upper shore into the sub-littoral. Periwinkles are usually picked off the rocks by hand or caught in a drag from a boat. In Marine Ecology: A Comprehensive, Integrated Treatise on Life in the Oceans and Coastal Waters, vol. Littorina littorea has various biochemical adaptations that allow the stressful intertidal habitat to be exploited. We investigated grazing and growth rates of the littorinid species, Littorina littorea and L. obtusata, when offered Fucus vesiculosus, Ascophyllum nodosum, Ulva lactuca, and Chondrus crispus, highlighting distinctive vulnerabilities.

L. littorea is oviparous, reproducing annually with internal fertilization of egg capsules that are then shed directly into the sea, leading to a planktotrophic larval development time of four to seven weeks. Merseyside BioBank Active Naturalists (unverified). Female specimens have been observed to be ripe from February until end of May, when most are spawning. (2010). Although Littorina littorea (L.) exhibits a relatively consistent pattern of vertical distribution throughout the North Atlantic, ranging from the mid-intertidal to the shallow subtidal zone, its horizontal distribution and abundance are highly variable. During the breeding season males are easily distinguished by the presence of a penis on the right hand side of the body. Growth and production of a Littorina littorea (L.) population in the Bay of Fundy. The actual value is depending upon supply and demand, with seasonal variations. Oxford: Oxford University Press. This makes winkles the sixth most important shellfish harvested in Scotland in terms of tonnage, and seventh most important in terms of value. The common periwinkle is sold by fishmongers at seafood markets in large cities around the world, and is also commonly found in seafood restaurants as an appetizer or as a part of a seafood platter.  It is still collected in quantity in Scotland, mostly for export to the Continent and also for local consumption. Humans get them for food and Littorina littorea doesn't cause any harm to us.
