Baleen whales are a widely distributed and diverse parvorder of carnivorous marine mammals. There are currently 15 species of baleen whale. Baleen whales produce a number of vocalizations, notably the songs of the humpback whale (subspecies)
The meat, blubber, baleen, and oil of baleen whales have traditionally been used by the indigenous peoples of the Arctic. Once relentlessly hunted by commercial industries for these products, cetaceans are now protected by international law. Besides hunting, baleen whales also face threats from marine pollution and ocean acidification.
