Appearance

The shell is extremely small, oval-cylindric and obtuse at the summit, of a more or less deep brown, smooth and dull. This snail lives under hedges. (description as Vertigo heldi) The shell is rimate, turreted, irregularly and very finely striate, of reddish-brown color, glossy. The shell has 6 whorls, that are slowly increasing and rather convex.

The first 3 whorls form a blunt summit that is about ⅓ the length of the shell. The aperture is about ¼ the length of shell, arcuately convex, somewhat impressed on the outer side, the impression running as a groove-like depression for a short distance on the last whorl.

Range and habitat

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

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.
