Cecilioides acicula, common name the "blind snail" or "blind awlsnail", is a species of very small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Ferussaciidae.[2]

This is a subterranean species.

Description[]

This animal is white, there are two pairs of tentacles, but eyes are lacking.[3]

The shell is long and narrow, up to a maximum of 5.5 mm and a width of 1.2 mm.[4] The shell is colorless, glassy and transparent when it is fresh, a somewhat opaque milky-white when it is not fresh.

Habitat[]

The habitat of this species is underground, quite some distance below the surface. It is more common in soils with a high level of calcium.[4]

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

Distribution[]

Distribution of this species is central European and southern European.[5]

This species native range is Mediterranean Europe, specifically (Spain, …), Western Europe (Great Britain and Ireland,[6] Netherlands,[7] …) and Central Europe (Czech Republic - least concern (LC),[8] Poland, Slovakia, Ukraine[9] …).

It has also been accidentally introduced to several other countries:

  • Latvia since 2006[10]
  • Bermuda since 1861[11]
  • Canada: Ontario[12]
  • The United States (in Pennsylvania and in Florida,[13] in Maryland since 1959,[14] in Virginia since 2006,[15] in California, in New Jersey and in New Mexicoà[16]
  • New Zealand.[17]
  • Australia.[18]
