Abstract: The distribution and activity patterns of the limpet Collisella paradigitalis was studied. The vertical distribution was found to be .7 - 3.2 meters above MLLW with average density .27 meters below Endocladia zone. The limpets were found primarily in protected areas with 91% of the population found on vertical or slightly overhanging surfaces. On average, the limpets moved 13.4 cm during high tide, with larger limpets moving a greater distance. Very infrequent homing was found in 67% of the population.
