Grove Snail, Cepaea nemoralis
2013-10-14 10:20:27

The Grove 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 within Europe and has been introduced to North America. C. nemoralis is the type species regarding the genus Cepaea. It is used as a model organism in citizen science projects. This snail species is among the largest due to its polymorphism and bright colors. The color of the shell is very variable, reddish, yellow,...
