GiraffeUnlike the chimpanzees in the earlier image, this giraffe's body glows at a nearly uniform temperature in infrared light. Its fur is short and does not need to insulate against lost body heat.
Visible: A giraffe peers over a wall.
Infrared: The giraffe gives off a nearly solid glow in infrared light due to its uniform temperature. Note the cool hair of the tail, which is darker because it gives off less heat, and the brighter eyes and inner ear.
