The humpback whale lives in the North Pacific Ocean and feeds on krill, plankton, and small fish. It uses bubbles to herd its prey and has a scientific name meaning "large-backed." Humpback whales were nearly hunted to extinction but are now protected, though their habitat is still threatened by pollution and entanglement in fishing gear. Conservation efforts aim to educate the public about not littering in the ocean and respecting marine wildlife.
