Frog On Cabbage
Photograph - Digital Photograph
Pacific tree frog trying to hide on a red cabbage leaf, and not really doing a very good job. The Pacific treefrog changes color based on the air temperature and humidity. The frogs don't control this change; it just happens naturally within a few minutes. The color change is for exactly the reason you think -- a defense mechanism to reduce the likelihood that the treefrog will become a meal for a bullfrog, raccoon, heron, snake, or other predator.
