The Daudebardia (Daudebardiidae) are a family of predatory snails from the superfamily Gastrodontoidea in the subordination of the land snails (Stylommatophora). They are half-slugs; only the young can fully withdraw into the housing. The adults are half-slugs that only have a tiny shell on the coat.

features

The animals measure stretched out to max. 5 cm in length. The housings are flattened with about 2 turns and only a few millimeters in size. The last turn is very much expanded. The young animal can still withdraw into the housing. In the further course of growth, the shell remains in its development and the animal becomes a half-slug, the shell sits as a small cap on the rear part of the mantle. They can be stretched to several inches tall.

Occurrence and way of life

The range of the family extends from about the Middle Rhine area in the west to southern Ukraine in the east, Kurdistan in the southeast, across the Middle East, various Mediterranean islands (Cyprus, Crete) and in North Africa (Algeria). The animals live in the mountains and hills under stones or thick layers of leaves. They predatorily feed on earthworms, insects and their larvae, as well as other snails.

Systematics

The Daudebardia family is now often counted as a subfamily to the family of gloss snails (Oxychilidae), which is usually also placed in the superfamily Gastrodontoidea. Other authors include them in the superfamily Zonitoidea or Limacoidea . According to Hausdorf (1998), however, they are classified as the sister group of the Gastrodontidae and thus with the Gastrodontoidea.
