Littorina obtusata, common name the flat periwinkle, is a species of sea snail, a marine gastropod mollusk in the family Littorinidae, the winkles or periwinkles.[1]

Distribution[edit]

This marine species occurs wherever brown seaweeds grow. It is widely distributed : the Baltic Sea, in European waters from Norway down to Southern Spain, in the Mediterranean Sea, in the Northwest Atlantic Ocean along the Gulf of Maine.

Description[edit]

The maximum recorded shell length is 13.5 mm.[2]

Habitat[edit]

This species can be found in the littoral and sublittoral zone on rocky shores and piers, usually on brown algae of the genus Fucus. Minimum recorded depth is 0 m.[2] Maximum recorded depth is 110 m.[2] The habitat defines its color. On sheltered shores it has a lighter and uniform color (yellow, brown, orange or olive green). On exposed shores its color is darker and chequered.
