Drawings of a shell of Cochlostoma septemspirale

The shell is light greyish brown with 3 rows of reddish brown spots.[4] It has 6-8 regular ribs/mm and 7-10 convex whorls.[4] The aperture is inside whitish.[4] There is no significant sexual dimorphism on the shell.[4]

The width of the shell is 3.2-4.4 mm.[4] The height of the shell is 6.7-10.2 mm.[4]

The animal is medium-sized (5-6.5 mm long), greyish with weak brownish hue.[4]

Cochlostoma septemspirale lives in forest habitats, rocks, rock rubble, walls and grassy slopes, up to 2100 m.[4]

It feeds on disintegrating plant substrate, sometimes also on the algae film growing on limestone.[4]

The animal is slow, not very active, and very shy. However the animal will emerge when put onto a cold object.[4] It is active only in wet weather, and the operculum is closed when the soil is dry.[4] This snail climbs trees up to 2 m during very wet weather conditions.[4] It hibernates between stones, under leaves and grasses; activity seems to cease when temperatures go below 6-7 °C.[4]

Eggs (diameter 1.0-1.1 mm, occasionally down to 0.6 mm) are laid from April to October, mainly during May to June, about 1 cm below the surface.[4] The eggs are covered by the female with faeces and mucus. They are laid in clutches of up to 10 eggs.[4] Juveniles hatch after 45–60 days, and the full adult shell size is reached after roughly 1 year.[4]
