Communication and Perception
Pollock rely on their lateral line system for schooling. Pitcher et al. (1976) covered the eyes of schooling ollock with opaque patches to demonstrate that vision is not necessary for schooling behavior. However pollock are not able to school if their lateral line has been severed, evidence that it is important for schooling. Pollock may use vision for prey detection and capture and for mating.
