The Round Mouthed Snail (Pomatias elegans) is a small, air-breathing, terrestrial (land) gastropod mollusc in the Pomatiidae family of operculate land snails. It is an invertebrate, because it does not have a backbone. Its shell is its exo-skeleton (outside skeleton).
The Round Mouthed Snail has a thick, whitish, conical shell and wide mouth with a chalky operculum (lid) at the rear of its body. The shell forms a whorl. The top of the spire points upward and the opening of its mouth is on the right – so it has a right-handed whorl, which is called a dextral shell. It can close its shell’s mouth with its lid. Its head extends to form a snout (proboscis). It has only one pair of tentacles on its head (instead of two pairs). Its eyes are at the tip of the tentacles.

The Cambodia Land Snail (Amphidromus atricallosus classiarius) is a tropical, air-breathing invertebrate gastropod mollusc in the Camaenidae family of arboreal (tree-living) pulmonate land snails. An invertebrate does not have a backbone and gastropod means stomach-footed.
The Cambodia Land Snail can be varied in colour, often quite colourful but a few species can be dark, with a smooth shell that can be thin and fragile or heavy and solid. Different species have different colours, and can have varied number of whorls, and the direction of the way its shell spirals.
