We been looking at cold and warm blooded animal using an infrared camera.  In the first picture, I am holding a fish in my hand for a few seconds.  We can see that the fish is blue, indicating that it is cold and that my hand is yellow and red, indicating that it is much warmer.

In the second picture, we see the contrast between a hand and the beans we are growing.

The third picture shows a hand next to a flower.  Notice that the flower is not at the same temperature everywhere.
