The North Pacific right whale is a critically endangered species of baleen whale found primarily in the North Pacific Ocean. It is characterized by its large size, with adults reaching lengths of up to 50 feet. These whales have a robust body, a broad back, and a distinctive lack of dorsal fin. They primarily feed on small zooplankton, using their baleen plates to filter food from the water. Historically, the North Pacific right whale was heavily hunted for its blubber and baleen, leading to a significant decline in its population. Today, fewer than 30 individuals are estimated to remain, making conservation efforts crucial for their survival. The species is protected under various laws, including the Endangered Species Act, and efforts are ongoing to monitor and protect their habitat.
