Vertigo is a genus of minute, air-breathing land snails, terrestrial pulmonate gastropod molluscs or micromollusks in the family Vertiginidae, the whorl snails. [2]
Snails in the genus Vertigo have no oral tentacles, thus they have only one pair of tentacles.
The jaw is arched; the ends squarely truncated; the anterior surface striate; the cutting edge with a median projection. The radula has a central tooth that is almost square, tricuspid, as large as or larger than the lateral teeth, which are similar, narrower, and bi- or tricuspid. The marginal teeth are low, wide and serrated.[3]
The shell is deeply rimate and ovate. The apex is acuminate and obtuse. The shell has 5–6 whorls. The last whorl is rounded. The aperture is semioval with 4 to 7 folds. The peristome is scarcely expanded and white-lipped.[3]
The distribution of the genus Vertigo includes Europe, northern Asia, eastern Asia, Japan, Central and North America, Caribbean and the Bermudas.[4]
