Anatomy

This snail is unusual in that it extends its almost transparent mantle to completely cover the shell when it is in motion, giving the very small animal a glass-like appearance. It also makes the animal sticky to the touch, hence its common name.

Shell Description

The shell is 13 to 16 mm in height and 11 mm to 15 mm in width in the adult. The upper whorls are almost flat so that the shell has a short blunt spire, the last whorl is inflated and predominating. The aperture is more than 90% of the shell height. The umbilicus is closed. The shell colour is brown or green, extremely thin and very transparent and shiny.
