Habitat
They inhabit the North Pacific Ocean, primarily in coastal and continental shelf waters from the Bering Sea south to Baja California. In summer, they frequent subarctic feeding grounds rich in plankton, and in winter, they migrate to warmer calving areas. This species prefers productive, nutrient-rich waters for foraging.
Diet
North Pacific right whales primarily feed on zooplankton, including copepods and krill, which they filter from the water using their baleen plates. They employ skim-feeding techniques near the surface, often during summer months in high-latitude feeding grounds. Feeding behavior is most active in daylight hours when prey is abundant.
Behavior
These whales are typically solitary or form small groups of up to a dozen individuals, exhibiting long-distance migrations between feeding and breeding areas. They are known for surface activities like breaching, lobtailing, and spyhopping, which help them communicate and scan their environment. They are slow swimmers, making them vulnerable, and use low-frequency calls for long-range communication.
Conservation Status
The IUCN classifies the North Pacific right whale as Critically Endangered, with a decreasing population trend due to historical whaling, ship strikes, and entanglement in fishing gear. Conservation efforts focus on reducing human impacts and protecting migration routes.
