What is Camouflage? How is it Helpful?
Why does an Arctic fox grow brown fur in the spring and white fur in the winter?
As scientists, you always want to question any and all information you read. Often writers, including myself, tend to give animals behavior and thinking abilities they do not posses. See if you can find examples of giving animals thinking abilities they do not have in the following list of camouflage facts.
Some animals change colors not to camouflage themselves, but to express their mood. Chameleons can turn yellow, dark blue, or even black if they become angry.
Fact: The mood of an animals changes in response to events. But the animal does not make a mental decision to change its color to express its mood. Instead, when you or animals are angry there are different physical and chemical changes in your body. Your face might get red, while the skin of a chameleon might turn other colors.
1. Some animals change their appearance as their surroundings change:
An octopus can change the color and texture of its skin extremely quickly in order to hide in the changing terrain of the ocean floor.
An Arctic fox will change the color of its fur based on the seasons. In the warmer months, the Arctic fox will grow brown fur to hide in the trees, and in the winter, it will grow white fur to hide in the snow.
2. Some animals have special patterns, or markings that help them blend in with each other and confuse predators. For example, zebras use their stripes to confuse their main predator, lions.
3. Animals can use camouflage to help them remain hidden from predators, particularly those who primarily hunt using vision instead of smell.
4. Mimicry is a form of camouflage in which an animal resembles another animal.
Some harmless snakes—and even some caterpillars—mimic rattlesnakes in appearance and behavior in order to be left alone.
The robber fly’s resemblance to a bumblebee makes predators give it a wide berth.
