Sažetak
The objective of this work was to make periodic observations of hypogean Zospeum isselianum Pollonera 1886 snails on a sample rock surface in the Jama pod Mokrico cave in the Kamniške-Savinjske Alps and monitor the distance the snails moved over a given period of time. Between April 30 and August 1, 1997, the movement of the snails was recorded thirteen times. The air temperature in the cave was between 6.0 °C and 10.2 °C, and the relative humidity was between 97% and 100%. The snails moved over distances of from 1 to 15 cm per week. The average distance was 0.7 cm per day. The snails generally crept around the places they were initially found.
