The rate of daily movement in the field of individuals of Clibanarius vittatus was recorded at a north Florida site. The mean daily movement for 82 crabs was 156 m. Neither crab size, sex, species of shell inhabited, nor absolute size of shell inhabited explained any of the variance in movements. For females only, the deviation in weight of shell occupied from the preferred shell weight was correlated (r = +0.46) with extent of daily movement.

Two factors which were significant in explaining variance in the rate of movement were substrate type (high rate on open sand, low on oyster rubble) and phase of tidal cycle (low rate during high tide). I suggested that both resource acquisition rates and predation pressures contribute to the patterns of movement observed.
