Cecilioides acicula, also known as the blind snail or blind awlsnail, is a subterranean species of very small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Ferussaciidae.[4]

Description

Cecilioides acicula is white, eyeless, and has two pairs of tentacles.[5]

Their shell is long and narrow, with a maximum length of 5.5 mm and a maximum width of 1.2 mm.[6] Fresh shells are colorless, glassy and transparent, while less fresh shells are an opaque milky-white.

Habitat

Cecilioides acicula is a subterranean species, most commonly found in soils with a high level of calcium.[6]

Due to its subterranean habitat, this species is often found as an empty shell in places such as mole hills, ant hills, or in flood debris of rivers.

Distribution

The native range of Cecilioides acicula is Mediterranean Europe, specifically Western Europe (Great Britain and Ireland,[7] Netherlands,[8]) and Central Europe (Czech Republic,[9] Poland, Slovakia[10], Ukraine[11]).

It has also been accidentally introduced to several non-native countries:
