Have you ever wondered why some animals have such crazy looking sense organs? Why do snakes have a split tongue? Why do elephants have such huge ears? Why do some bats have different looking ears and noses? Why do moths have antennae that look like feathers? Every feature has a special purpose that has evolved to ensure the survival of the animal. Just like us, animals rely on their senses to communicate with each other, to nd their way around,to find food and to stay safe.
