Species spotlight I

Ferussacia folliculum (Gmelin, 1791)
Munxar, Għawdex

Ferussacia folliculum (Gmelin, 1791) is a common tiny snail which lives in a variety of habitats, as long as sufficient cover from the sun's heat is present. It is usually found in moderate to large-sized populations, such as the one composed completely of juvenile individuals, as shown below (photo taken in Pembroke, Malta):

The shell is brown and quite glossy. The yellowish colour visible in the above picture is imparted by the snail's foot, as is shown better thanks to the 'one that got away':

Shell identification
  • glossy brown shell
  • transparent when fresh
  • large last whorl
  • tall and pointed
  • relatively thick shell
  • tooth at the base of aperture
