Distribution

Distribution of Zonitoides excavatus include:

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]
