I saw a video during class and mimic octopus was so interesting to me. So.. I search more about camouflage animals. Animals have to avoid enemy’s observation to survive. Of course, if they have big-built and sharp teeth, they can defeat the enemy. But, small and weak animals have to avoid notice themselves. Hiding (camouflage) is the best way to survive. Also, people crouch down body instinctually or mingle in crowd when they facing danger, but these are usually happen in urgency situation. However, many animals can hide themselves in peaceful situation. They disguise themselves as surrounding environment. There are many animals that have patterns. Big cats like tigers have stripe pattern to hide themselves. In empty cage (zoo), that stripe can see (find) easily and looks beautiful, but in forest, it helps them to hide. And, some animals make flat their body, because dimensional body disrupts hiding. Also, there are animals that have similar color with surround. For example, green frogs live on big green leaf, Arctic animals have white body and bottom fish have golden body. And some animals can change their color to mingle in surround color every single time. Like these, animals are so amazing.
