The 3-6 x 5-11 mm
shell has 5-6 moderately convex
whorls which are rounded or very slightly keeled at the periphery. The
aperture has a thin white
lip inside. The
umbilicus is open and usually wide at 1/8-1/4 of shell diameter. In colour the shell is brown to cream, sometimes with a light band at the periphery. The
periostracum is irregularly striated, and densely covered with short (0.2-0.3 mm), curved hairs. These hairs usually remain in the umbilicus if worn away from the rest of the shell. Lost hairs leave pronounced scars.[6]
The animal is brownish grey with a darker anterior part.[6]
Anatomy
This species of snail creates and uses
love darts before mating. The love dart of this species is
thorn-shaped.
Shepeleva (2014) studied
eyes of Trochulus hispidus.[7]
A hairy snail was found in the plumage of a
great tit (Parus major) wintering in southwestern Poland in 2010. This
passerine was the smallest bird species reported to carry a gastropod.[9]
