Endangered
Plagigeyeria zetaprotogona
Plagigeyeria zetaprotogona
Plagigeyeria zetaprotogona is a dawhilahila.
The springsnail
It was first described by Franz Schütt in 1960.
Hydrobiid snails are tiny operculate gastropods of springs, streams, and caves. A named species may occupy one drainage.
This snail order mixes marine periwinkles with tiny freshwater and spring taxa. The shared trait is an operculum in most families.
Range and habitat
Plagigeyeria zetaprotogona is recorded from Montenegro and Albania.
GBIF currently lists 23 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
Springsnails graze biofilm in cold, stable water. A dried spring or a pumped aquifer can remove the only known population.
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
A springsnail listed from one source is one drought or one borehole away from an empty name.
