Vinodolia matjasici

The springsnail

It was first described by Bole in 1961.

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

No country pin is stored for Vinodolia matjasici on this catalog. That is a missing field, not proof the animal has no range.

GBIF currently lists 2 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.

Vinodolia matjasici 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.
