The species tends to aggregate and form clusters in areas . Periwinkles are a large family of gastropod molluscs found on the shore. The edible periwinkle is perhaps the best known species of this family, as it has been collected and eaten for centuries.

Littorina littorea has various biochemical adaptations that allow the stressful intertidal habitat to be exploited. This species is the largest periwinkle . Alternate common names: Periwinkle, Winkle. Seasonal appearance: All year. The range of the periwinkle.

North America extends from Labrador to New Jersey. Egg capsules are shed directly . Shells have been found at . Falmouth, Massachusetts. Kate Buckman, Annette Hynes, and Elizabeth Orchard.

The intertidal community is an interesting ecosystem to study because of its . Common name, Common periwinkle. Systematics and evolution of Littorina. Lakeland Molluscs, p 13. Schelpen Encyclopedie (in Dutch), p 60.

Characteristics: The common periwinkle can grow to a height of more than cm. Black, brown and grey are common colors, but white, orange and even red is not unusual. The spiral ridges are clearly visible on juveniles, but tend to be worn out as the snail grows older.

The shell cone is pointing backwards. Noventa S(1), Pavoni B, Galloway TS. Seaman B(1), Briffa M(2).
