These are the familiar land snails and slugs: air-breathing gastropods with a lung, not a gill.
Gastropods are snails and slugs. The animal is the soft body; the shell, when present, is grown, not worn like a stone.

Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
