The Alpine mud snail ( Radix labiata , syn .: Radix peregra (OF Müller, 1774)) is a water lung snail from the family of mud snails (Lymnaeidae).
features
The housing is tapered with about 4.5 to 5 turns. These increase relatively uniformly in height and width. The solid-walled shell is brownish or gray-brown with a purple sheen. The outline is straight; the edge of the mouth drops off the same steeply from the upper approach. The housings are 12-20 mm high and 7-13 mm wide.
Way of life and distribution
The species lives in small, stagnant or slowly flowing water. It also occurs in the mountains. It occurs in isolated occurrences in Central and Southern Europe up to Turkey and is relatively rare.
Similar species
The species can be very similar to the common pond snail . As a rule, however, this is wide and the mouth more curved. In extreme forms, however, only an examination of the bursa stalk in the female genital tract helps.
