Succineidae are a family of small to medium-sized, air-breathing, land snails (and slugs), terrestrial pulmonate gastropod molluscs. They are commonly called amber snails because their thin fragile shells are translucent and amber-colored. They usually live in damp habitats such as marshes.[1]

Succineidae is the only family in the superfamily Succineoidea.[2]

The animal is very soft and also appears to be too large for the shell.[1]
