Infrared light shows us the heat radiated by the world around us. By viewing animals with a thermal infrared camera, we can actually "see" the differences between warm and cold-blooded animals. Infrared also allows us to study how well feathers, fur and blubber insulate animals. As you tour this "Infrared Zoo", see what new information you can gather about the animals here that you would not get from a visible light picture. If you would like to learn more about infrared light and the infrared universe visit Cool Cosmos. Enjoy your tour!
Chickens are warm-blooded birds and generate their own body heat by converting the food that they eat into energy.
These warm-blooded ducks are covered with thick feathers which insulate them from the cold.
Since eagles are warm-blooded, they radiate their own heat.
This emu had been standing in hot sunlight before entering its shaded shelter to cool off.
Notice how the lizard's body temperature has risen as it basks in the sun!
These turtles have just walked out of pool of cool water. Notice how cold they still are.
The bright areas on the baboon's body are places where her fur is thin, allowing her body heat to escape more easily.
In the infrared images, you can see the cat's warm glowing eyes and the heat from the cat's ears and mouth area.
Notice how cool the dog's nose is!
Notice how cool the tip of the elephant's trunk is after being in the water.
Notice that their patches, which would appear brown in visible light, are warmer in the infrared, while the light beige (visible light) borders surrounding the brown patches are cooler in the infrared.
