Critically Endangered
Hemicycla modesta
Hemicycla modesta
Hemicycla modesta is a land snail in the family Helicidae (order Stylommatophora), recorded as Critically Endangered and tied to Spain and Denmark.
Appearance
The length of the shell attains 16.7 mm.
Range and habitat
It is endemic to the Canary Islands, Spain.
GBIF currently lists 64 occurrence points. Those points follow where people logged the taxon — museum drawers and surveys included — not a closed range boundary.
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
Hemicycla modesta is Critically Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
