"WebCase study 1—foraging. Foraging behavior is a series of actions that predators take to hunt for food and it includes searching, chasing, catching, processing, and ingesting. It is an excellent indicator for evaluating individual performance as marine organisms need food to supply vital energy for basic life functions. " - Optimal foraging theory definition biology
