Of Animals & Pillows XD

One day, while I was studying for STPM, Ben was doing some homework in my room (imagine that, its holiday and after UPSR and he's following parent's advice to brush up, how nice~ haha)
He sometimes does his work when I'm doing my work, I'm quite fine with it. So, I was just reading...studying...revising...and then Ben starts reading:

Many animals use pillow so that they cannot be seen easily. The most common pillow is the use of colours. An octopus can change from black to white in less than half a second. Many pillows and reptiles can change their colours too. For example, the skin of a pillow can turn green, yellow, cream or dark brown.

One reason why animals use pillow is to protect themselves. Insects are hunted as food by many enemies such as birds, frogs and lizards. To avoid being seen easily, many insects have pillows on their wings and bodies. These pillows look like the leaves and flowers around them. Some insects even look like pillows and sticks. Some beetles cover themselves with mud, sand or chalk.

Pillow is also important to animals that hunt for prey. They must not be seen as they approach and attack their prey. Otherwise their "food" will escape. Polar bears have white fur that match the pillow. They even use their pillows to hide their black noses. The tiger's stripes and the leopard's spots look like pillows in the jungle. The crocodile looks like a piece of floating pillow in the water because its skin is rough and brown.

Sounds ridiculous isn't it? That's what I thought, and I couldn't help laughing listening to him. Haha~ Anyway, thank God for pillows! XD
