Killer whale hunts are meticulously coordinated attacks where groups of 15 or more killer whales target gray whale calves and their mothers off the coast of California. The killer whales tire out the mother, separate the calf, and brutally attack by ramming the calf's side, breaking the lower jaw to prevent it from breathing, making it easier to drown. These hunts involve killer whales of various ages in a highly coordinated manner, showcasing cultural distinctions in hunting techniques among ecotypes.
