Zonitoides excavatus is a European species of small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Gastrodontidae.
Distribution
Distribution of Zonitoides excavatus include:
- British Isles: Great Britain and Ireland. In Britain it restricted to a few regions, but frequent in the zones where it occurs (Cornwall, south of London, west Wales, southwest and northwest Ireland, central England, southwest Scotland).[2]
- Endangered in Germany (2009).[2]
- Denmark[2]
- Belgium[2]
- northern France.[2]
Description
Zonitoides excavatus is smaller than Zonitoides nitidus.[2] The umbilicus is extremely wide and perspectivically open (as is the case in Discus rotundatus).[2] The shell is weakly brown, slightly transparent, with radial streaks.[2] The animal is dark.[2]
The width of the shell is 5.3–6 mm, and the height of the shell is 2.8-3.4 mm.[2]
Ecology
Zonitoides excavatus lives in leaf litter and under dead wood in old natural forests, sometimes also in swamps (western Ireland and western Great Britain).[2] It lives only on non-calcareous soils.[2] It tolerates some degree of human disturbance and replanting, but usually not in forest plantations.[2]
