Some whales, such as the bowhead whale, have baleen of differing ...
Baleen whales can have streamlined or large bodies, depending on the feeding behavior, and two limbs that are modified into flippers. The fin whale is the fastest baleen whale, recorded swimming at 10 m/s (36 km/h; 22 mph).

Baleen whales have two blowholes. Some species are well ...
Baleen whales - a group that includes the blue whale, the largest animal in Earth's history - use a larynx, or voice box, anatomically modified to enable underwater vocalization, researchers said ...
