Abstract: This study examines the effects of several factors on the random movement of the bat star, Patiria miniata. Individuals, about 40 was the average, were placed at a marked spot and released immediately around it, as close as possible without stacking. Movement from this center was recorded with respect to the factor involved. It was found that P. miniata move randomly if no factor interveins, away from shallow water and away from detached algae rolling on the bottom with the surge. They are not influenced by the proximity of rocks, although they will remain on one if placed there, nor by the presence of dead Mola mola on the bottom.
