...ankton density in both the horizontal and vertical dimensions and adjusting their behavior accordingly. In the horizontal dimension, the path of a feeding whale is sinuous, with many turns, as it attempts to remain within the area of maximum copepod density. In the vertical dimension, whales feeding on zoopla...... nature of the shape of the coating (i.e., pattern dimensions and surface energies), might be repugnant to the fouling organisms.
