Gastrodontidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Gastrodontoidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).^[3]

Distribution

The distribution of the Gastrodontidae includes the Nearctic, western-Palearctic, eastern-Palearctic, Neotropical and Hawaii.^[4] There are some representatives in Bermuda and Madeira.

Some snail species in this family use love darts made of cartilage.

In this family, the number of haploid chromosomes lies between 26 and 30 (according to the values in this table).^[5]
