geneticist: Leaf insects use camouflage to take on the appearance of a leaf. They do this so accurately that predators often aren’t able to distinguish them from real leaves. In some species the edge of the leaf insect’s body even has the appearance of bite marks. To further confuse predators, when the leaf insect walks, it rocks back and forth, to mimic a real leaf being blown by the wind. (OP)
