According to studies by Newell (1956), the distribution of periwinkles appears to have no relation to light, tidal level, or beach slope; periwinkles can be found in clusters, especially in crevices and tide pools, or alone.

Why do periwinkles cluster together?
While the Little Blue Periwinkles can survive losing up to 70% of their water content, their waterproof shell and a mucous they produce to seal the opening of their shell helps to reduce evaporation. ... The Little Blue Periwinkles will cluster together creating a humid microclimate further reducing water loss.
How does periwinkle survive?
Common periwinkles can live for many days without food or water by retaining moisture in their gills. They close themselves into their shells and excrete a sticky mucous that hardens, firmly attaching the animal to the rock or blade of seagrass.
How does periwinkle reproduce?
Periwinkles have separate sexes (individuals are either male or female). Reproduction is sexual, and females lay eggs in capsules of about 2-9 eggs. These capsules are about 1mm in size. After floating in the ocean, the veliger hatches after a few days.
Where do periwinkles live?
Habitat. Periwinkles are marine snails found in the North Atlantic. They occur along the northeastern coast of North America, with a range that begins in Newfoundland and Labrador and ends in New Jersey. Periwinkles are abundant within their range, found at depths ranging from the intertidal zone to 40 metres below.
Where do periwinkles live intertidal zone?
Habitat. The common periwinkle is mainly found on rocky shores in the higher and middle intertidal zone. It sometimes lives in small tide pools. It may also be found in muddy habitats such as estuaries and can reach depths of 180 feet (55 m).
What animal lives in a tide pool?
Many animals make the tide pool home. These animals include sea stars, sea urchins, sea cucumbers, barnacles, and anemones. The Pacific octopus also makes the tidepool home. The octopus is related to the squid, but lives in rocks and caves instead of the open sea.
Can periwinkles live in freshwater?
Periwinkles can survive in fresh water — like puddles made by rain — for several days. ... A periwinkle, like most molluscs, uses a radula (a rough tongue or band of teeth) to scrape diatoms and algae from rocks.
Why is periwinkle called flower of death?
Periwinkle, an evergreen trailing groundcover, is a common invader throughout most of the United States. It is native to Europe, where it was commonly known in folklore as the “flower of death” because its vines were woven into headbands worn by dead children or criminals on their way to execution.
How long do periwinkle flowers live?
Is The Periwinkle Flower An Annual Or Perennial? Normally, the vinca minor plant lasts only one year, however, that depends on where the periwinkle plant is growing. In northern climates, this ornamental plant would be considered an annual that usually last for only one year.
What do periwinkles turn into?
Gradually they grow a shell, transform into tiny periwinkles, and settle to the bottom of the subtidal zone. According to the literature, periwinkles then move up into the intertidal zone and become sexually mature within 18 months. During these months periwinkles can grow to be 18 millimeters in shell height.
What do periwinkles feed on?
The edible periwinkle feeds by grazing on algae on the rocks using its rasping tongue, called a radula. They don't like dry areas, so will often be spotted clumped together in a crevice or rockpool at low tide.
How do I grow periwinkle?
Space plants at least 12 to 18 inches apart. Plant out periwinkle in spring or early fall. Water the soil deeply after planting and keep the soil evenly moist during the first 6 to 10 weeks, as the roots become established. Fertilize periwinkle in spring with ¼ cup 10-10-10 fertilizer per 100 square feet of soil.
How do periwinkles breathe?
It feeds on algae by scraping the rock surface with its radula or tongue. The rough periwinkle can survive for extended periods of time with little to no oxygen, using anaerobic metabolism to obtain energy. It also has a lung-like organ, similar to land snails, that allows it to breathe air directly.
Why do periwinkles live in high tide?
Blue-grey periwinkles (Austrolittorina spp.) are especially adapted to the harsh conditions of the dry upper littoral zone. They are able to trap water inside their shell to prevent moisture escaping, and cling to the rock face while the tide is out.
Do periwinkles live on rocks?
Common periwinkles are often found in high densities on rocks. Although most common on rocks, periwinkles can inhabit sandy and muddy areas. Common periwinkles are masters of the intertidal zone, and are well adapted for long periods of time both in and out of water. ... Periwinkles cling tightly to rocks during low tide.
