Common Periwinkle

Littorina littorea

Common Periwinkle (Littorina littorea)

Also called the ‘Edible Periwinkle’, the shell is variable in colour, from black and grey to brown, white or red, and usually patterned with spiral dark lines. It is conical in shape with a pointed apex. This is the largest British periwinkle, but is usually smaller than 50mm.

It favours rocky shores upper to lower zones with a good covering of seaweed. It can also be found in mud-flats or esturaries. The Common Periwinkle is a herbivore which grazes on seaweeds. Widespread and abundant throughout.

Following The Snail Road

Strawberry Snail (Trochulus striolatus)

It still never fails to amaze and fascinate me how Mother Nature has created so many diverse forms of life. And how these differing forms of life have evolved and adapted to their given environments in order to survive the rigors of life. Take the shell of this Strawberry Snail, how beautifully formed and crafted it is, how fine and delicately sculptured, taking the artist millions of years to perfect. Yet, the work is never complete, such is evolution.

I came across the snail pictured in the above two photographs as it was going down to the pond this morning. It is a relatively small snail with a shell diameter of around 12mm.

They are found in woodland, hedgerows and gardens. Common and widespread, but scarce and localised in Scotland.
