[Note Guidelines] Photographer's Note
The grove snail or brown-lipped snail (Cepaea nemoralis) is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk. It is one of the most common species of land snail in Europe.

Apart from the band at the lip of the shell, grove snails are highly polymorphic in their shell colour and banding. The background colour of the shell can sometimes be so pale as to be almost white; it can also be yellow, pink, chestnut through to dark brown, and the shells can be with or without dark bandings. The bands vary in intensity of colour, in width and in total number, from zero up to a total of six.

These polymorphisms have been highly studied as part research in heredity and evolution. They are thought to act as camouflage to avoid predation from, for example, the Song Thrush, but also have implications for the body heat of the animal: darker shells heat up more quickly, with consequences for rates of metabolism and loss of moisture (crucial in snail locomotion). In particular, grove snails with dark brown appear to preferentially be found in dark woodlands, whilst snails with light yellow shells and thin banding are more commonly found in grassland.

The grove snail can be found in a range of habitats: most commonly in grassland, hedgerows and woodland. Its native distribution is from northern and western Europe to central Europe (the Czech Republic and others). In eastern Europe it occurs urban areas.
More recently, the grove snail has been introduced to North America, and has established itself in various places.

The white-lipped snail has a similar range, but that species extends further north to border the Arctic.

Hello Ferran,
good to see you back on this site with a well made, silently unspectacular image that is coming with very interesting instructive notes plus workshop. I was not aware of that species' high degree of variability and their reasons.
Thank you for your contribution.
With best regards,
Peter

Hi Ferran,

Welcome back - it's so nice to see you again. This Snail is wonderful. Not something we see here in the desert. The colors and design are so beautiful and the details could not be sharper. The marvelous fresh leaves enhance the attractiveness of the snail even more. You have composed this perfectly.

Bonjour Ferran,
Heureuse de revoir une image de ta part.
Un posting très beau par l'image et très intéressant par son texte. J'aime beaucoup voir les coquilles d'escargot aux couleurs si diverses (je les collectionnais lorsque j'étais enfant). Tu as choisi un angle de vue pas facile pour obtenir une bonne netteté. Très belles couleurs naturelles aussi.
Un grand merci et une belle journée
Anne

Ferran,
PERFECTION.
Mario with friendly greetings from COLD COLD Canada.

Hallo Ferran
Wonderful capture of this beautiful snail. Straight forward presentation with super sharpness, focus and detail. Great composition. Vibrent and shiny colours with great markings on the shell. It can actually go through as a piece of art. A splendid piece of work, presented in a most delightful manner. Thanks for sharing.
Kind regards
Anna
