Baleen is similar to bristles and consists of keratin, the same substance found in human fingernails, skin and hair. Baleen is a skin ...
The whale lungs are very efficient at extracting oxygen from the air, usually 80%, whereas humans only extract 20% of oxygen from inhaled air.

Unlike ...

The mouth has a large, upturning lip on the lower jaw that helps to reinforce and hold the baleen plates within the mouth.
The Ningen is described in two forms; one has it as a large, aquatic, whale-like creature with anatomical similarities to humans, such as a distinct, humanoid face; sometimes it is given extremely large limbs and/or arms and hands, about 20–30 m (65–100 feet) long. The second, less common, description portrays it as a considerably smaller ...
