The video features a close-up of a mandrill, a primate known for its vibrant and colorful face. The mandrill's face is predominantly blue with red markings around the nose and mouth, and it has a bright orange and yellow chest. In the video, the mandrill opens its mouth wide, possibly in a yawn or a display of dominance, showing its teeth. The background is blurred, focusing attention on the detailed and striking features of the mandrill's face. The overall scene captures the unique and vivid appearance of this fascinating animal.
A baboon with a vibrant blue and red face and brown fur is seen in a green background. The baboon opens its mouth wide, appearing to be in the middle of a vocalization or yawn. It then begins to close its mouth slightly while still holding its hands close to its face. The baboon continues to close its mouth further, moving its head slightly to the side. Finally, the baboon turns its head to face the camera directly, opening its mouth wide again as if to yawn or make a sound.
