WHAT DO YOU KNOW ABOUT PERIWINKLE

Do you know that we have at list tree type of periwinkles? anyway i will be talking about the Two common type that i know off:

1. PERIWINKLE (THE PLANT): Is an old world plant with flat five-petalled flowers and glossy leaves. Some are grown as ornamental and some contain alkaloids used in medicine.

In this article i will tell you how periwinkle is a name of a color: For other uses, see Periwinkle

Periwinkle is a color in the blue and purple family. Its name is derived from the lesser periwinkle or myrtle herb (Vinca minor) which bears flowers of the same color.

The color periwinkle is also called lavender blue. The color periwinkle may be considered a pale tint of blue or a "pastel blue".

The first recorded use of periwinkle as a color name in English was in 1895.In popular culture
Periwinkle blue is the color for esophageal and stomach cancer awareness ribbons, and for anorexia nervosa and bulimia. It is also the color for pulmonary hypertension awareness ribbons.
The "downvote" of the popular website Reddit is identified as periwinkle, and one of the two "teams" of the site's April Fools event in 2013 was named for the color.
Periwinkle was added to the Crayola palette in 1958.
Periwinkle is Tinker Bell's sister in Tinker Bell and the Secret of the Wings

1. The second PERIWINKLE: Is the common periwinkle or winkle (Littorina littorea) is a species of small edible sea snail, a marine gastropod mollusc that has gills and an operculum, and is classified within the family Littorinidae, the periwinkles.
   
   This is a robust intertidal species with a dark and sometimes banded shell. It is native to the rocky shores of the northeastern, and introduced to the northwestern,Atlantic Ocean.

The shell is broadly ovate, thick, and sharply pointed except when eroded. The shell contains six to seven whorls with some fine threads and wrinkles. The color is variable from grayish to gray-brown, often with dark spiral bands. The base of the columella is whiteThe shell lacks an umbilicus. The white outer lip is sometimes checkered with brown patches. The inside of the shell has a chocolate-brown color.

The width of the shell ranges from 10 to 12 mm at maturity,with an average length of 16–38 mm.

Shell height can reach up to 30 mm 43 mmor 52 mm.\

As a result of its robust nature, Littorina littorea can be highly variable in phenotype with several different morphs present. Its phenotypic variations may be indicative of a speciation event, as opposed to phenotypic plasticity. This is of particular importance to evolutionary biology, as it presents the possible opportunity to view a transitional phase in the evolutionary life of an organism.

Common periwinkles are native to the North-eastern coasts of the Atlantic Ocean, including northern Spain, France, England, Scotland, Ireland, Scandinavia, and Russia
Introductions to North America

Common periwinkles have been introduced to the Atlantic coast of North America, possibly[vague] by rock ballast in the mid-19th century. The first recorded case was in 1840 in the Gulf of St. Lawrence.It is now a predominant mollusc from New Jersey northward to Newfoundland. It was accidentally introduced to the North American East Coast within the last few centuries and it is now extraordinarily abundant on New England rocky shores. In Canada, their range includes New Brunswick, Nova Scotia, Quebec, Newfoundland and Labrador.

This species is also found on the West Coast of the United States, from Washingtonto California. L. littorea is now the most common marine snail along the North Atlantic coast. It has changed North Atlantic intertidal ecosystems via grazing activities, altering the distribution and abundance of algae on rocky shores and converting soft-sediment habitats to hard substrates, as well as competitively displacing some native species.The presence of this species has caused extensive damage due to interspecific competition with native inter-tidal gastropods.
Ecology
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 inmuddy habitats such as estuaries, and can reach depths of 180 feet.
Feeding

L. littorea is an omnivorous, grazing intertidal gastropod.It is primarily an algaegrazer, but it will feed on small invertebrates such as barnacle larvae. They use theirradulae to scrape algae from rocks, and, in the salt marsh community, pick up algae from the cord grass, or from the biofilm that covers the surface of mud in estuaries or bays.

Phlorotannins in the brown algae Fucus vesiculosus and Ascophyllum nodosum act as chemical defenses against L. littorea.
Life cycle

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. Females lay 10,000 to 100,000 eggscontained in a corneous capsule from which larvae escape and settle to the bottom. This species can breed year round depending on the local climate.It reaches maturity at 10 mm, and lives five to ten years.
Human use

This species appears in prehistoric shellfishmiddens throughout Europe, and is believed to have been an important source of food since at least 7500 BC in Scotland. It is still collected in huge quantities in Scotland, mostly for export to the Continent, and also consumed locally. The official landings figures for Scotland indicate over 2,000 tonnes of winkles are exported annually. This makes winkles the sixth most important shellfish harvested in Scotland in terms of tonnage, and seventh most important in terms of value. However, since actual harvests are probably twice reported levels, the species may actually be the fourth and sixth most important, respectively

They are usually picked off the rocks by hand or caught in a drag from a boat. They are mostly eaten in the coastal areas of Scotland, England, Wales and Ireland, where they are commonly referred to as winkles or in some areas buckies, willicks, or wilks. In Belgium, they are commonly called kreukels or caracoles. They are commonly sold in paper bags near beaches in Ireland and Scotland, boiled in their local seawater, with a pin attached to the bag to enable the extraction of the soft parts from the shell.

Periwinkles are considered a delicacy in African and Asian cuisines. The meat is high in protein, omega-3 fatty acids and low in fat; according to the USDA National Nutrient Database for Standard Reference, raw snails in general are about 80% water, 15% protein, and 1.4% fat.

Periwinkles are also used as bait for catching small fish. The shell is usually crushed and the soft parts extracted and put on a hook.

Following their history as an ancient food source in Atlantic Europe, they are harvested and consumed in the Azores Islands by the Portuguese people, usually called búzios, the generic name for sea snails.

Similar foods are consumed by other maritime cultures throughout the world, such as the Chinese people. Periwinkles, or a similar species, are sold at the live seafood
