Whale species exhibit a wide range of feeding behaviours and diets. The primary distinction is between toothed whales (odontocetes), including orca and sperm whales; and baleen whales (mysticetes), which include species like humpback whales and fin whales. The specific diet of whales varies based on species, geographical location, and environmental conditions. Whales are adapted to their specific ecological niches, and their feeding behaviours reflect the abundance and distribution of their prey in their respective habitats. The BC coast provides critical foraging habitat for many whale species, and within our dedicated research areas this includes humpback whales feeding on small schooling fish (including herring) and krill; fin whales feeding on krill, plankton, and small schooling fish; northern resident orca feeding almost exclusively on salmon; and biggs orca feeding exclusively on marine mammals.
