Endangered
Gyraulus trapezoides
Gyraulus trapezoides
Gyraulus trapezoides is a dawhilahila.
The gastropod
It was first described by Polinski in 1929.
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
Gyraulus trapezoides is recorded from North Macedonia.
GBIF currently lists 14 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
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
Gyraulus trapezoides 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.
