Many animals hide(躲藏) to stay alive(活着的). They hide in many ways. Some animals hide in leaves, some animals hide in snow. Usually their colors or shapes help protect them. It’s hard to see an Arctic bear in snow. Its white fur helps protect it. Chameleons(变色龙) can hide by changing colors. Their skin turns the same color as what is around them. Some chameleons can change their colors in five minutes.
Many animals try to look bigger than they are to stay alive. Some animals can make other animals think they are very big. If they look very big, animals that are looking for food will run away. Bears can walk on two legs. They look very, very scary(吓人的). Some animals will run away from them.
Many animals try to stay around other animals. This helps them stay alive. Zebras stay close together so that they can help each other look out of danger. Seeing many stripes at once can also confuse(使眼花缭乱) animals that want to eat them. Some birds stay in a circle(一圈), each toward a different direction. In this way they can also help each other stay alive by looking around for animals that many want to eat one of them.
