Endangered
Caseolus calvus
Caseolus calvus
Caseolus calvus is a land snail in the family Geomitridae (order Stylommatophora), recorded as Endangered.
The land snail
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.
Range and habitat
No country pin is stored for Caseolus calvus on this catalog. That is a missing field, not proof the animal has no range.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Diet
Snails move on a single foot and feed with a rasping tongue. Island and spring species rarely recolonise once the site is emptied.
In crisis
Caseolus calvus is Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
