Iberus gualtieranus
Iberus gualtieranus
Iberus gualtieranus is a land snail in the family Helicidae (order Stylommatophora), recorded as Endangered.
Appearance
The shell is keeled and flattened, with marked ornamentation of spiral and radial costulae. In contrast, Iberus alonensis and Iberus campesinus have more rounded shells.
Range and habitat
Iberus gualtieranus occurs in limestone mountain areas of rocky substrate and sun exposure sub-desert environments with sparse vegetation. It sometimes also occurs in areas with more vegetation cover. This species is endemic to the southeastern Iberian Peninsula, Spain.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Diet
Land snails rasp plants and detritus with a radula and seal the shell in dry weather. Introduced predators and habitat clearing hit them hard.
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
Iberus gualtieranus is threatened by fires and by road construction that fragments its habitat.
