People think that if animals look almost the same, they live in almost the same way. The truth is that some animals live in special and surprising ways. Do you think all spiders build webs and eat insects? The water spider walks on water and catches fish. Have you ever heard of a frog helping its tadpole by carrying it on its back? That is what some kinds of frogs do. Do owls always make nests in trees? No. Burrowing owls live in holes like rabbits. Strangest of all, the angler fish makes a light in its body, like a firefly, so it can eat smaller fish that come to look at the light. These are just some of the strange animals that live on our planet.
