Zonitoides excavatus is a European species of small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Gastrodontidae.[3]
Distribution of Zonitoides excavatus include:
Zonitoides excavatus is smaller than Zonitoides nitidus.[4] The flat and shiny shell is tightly coiled.It is weakly brown or greenish brown, slightly transparent, with radial streaks.[4] The umbilicus is extremely wide and perspectivically open (as is the case in Discus rotundatus).[4] The animal is dark.[4]
The width of the shell is 5.3–7 mm, and the height of the shell is 2.8-3.4 mm.[4]
Zonitoides excavatus lives in leaf litter and under dead wood in old natural forests, sometimes also in swamps (western Ireland and western Great Britain).[4] It lives only on non-calcareous, acid soils.[4] It tolerates some degree of human disturbance and replanting, but usually not in forest plantations.[4]
