This study investigated the movement of Lepsiella vinosa on the West Head rocky shore during October 1976 and May 1977. Forty-eight individuals were marked in the October observation period and 100 individuals were marked during the May period. The movements of individuals were followed over 4 intervals that corresponded to conditions of high tide/daylight, low tide/night, high tide/night, low tide/daylight. A Perspex quadrat marked in a grid pattern in 1 cm or 2 cm intervals was placed over the study area and used to record the position of each individual.

Mean rate of movement in May 1977 (2.70 ± 0.59 cm/h) was greater than during October 1976 (1.11 ± 0.22 cm/h). At low tide, the rate of movement correlated with air temperatures, with lower movement rates at higher temperatures. At high tide, there was no variation in movement.
