Anisus spirorbis is a species of small freshwater air-breathing snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails. [2]

Anisus spirorbis may be a broad-whorled morphotype of Anisus leucostoma.[3]

Distribution

Europe to Siberia.

This species occurs in countries that include:

  • Czech Republic[4] – vulnerable (VU)[5]
  • Slovakia[4]
  • Germany – high endangered (Stark gefährdet)[6]
  • Poland
  • Ireland
  • Great Britain
  • Uzbekistan[7]
  • Siberia
