Zonitoides excavatus is a European species of small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Gastrodontidae.

[4] The umbilicus is extremely wide and perspectivically open (as is the case in Discus rotundatus).

[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 tolerates some degree of human disturbance and replanting, but usually not in forest plantations.
