Have you ever wondered why zebras have stripes on them? It is to help them hide inside the long grass. That the black stripes are a contrast against the green or orange of the grass is irrelevant because the zebra’s main predator is the lion, which is colour blind. Another reason is that all zebras look the same. A lion will try and pick the weakest animal , but when the herd is in danger and all the zebras run together they all look identical. So maybe the lion is fooled!
