Grove Unbanded Snail

The Grove Unbanded Snail (Cepaea nemoralis) is an air-breathing pulmonate gastropod mollusc in the Helicidae family of terrestrial (land) snails. It is also known as the Brown-Lipped Snail. It is an invertebrate, because it does not have a backbone. Its shell is its exo-skeleton (outside skeleton).

The Grove Snail can be varied in its appearance. The colour of its shell can be reddish, brownish, yellow, or creamy-white, with or without bands. The surface of its shell is semi-glossy. The shell has a right-handed whorl, which is called a dextral shell. The Grove Unbanded Snail’s shell is tan-brown and does not have prominent dark-brown bands or stripes. It has a white lip instead of a brown lip. Its head extends to form a snout (proboscis). It has tentacles on its head. Its eyes are at the tip of the tentacles.
