Orcas (Orcinus orca), also known as Killer whales, are easily recognized by their black-and-white markings on their bodies. More specifically, these whales have an iconic white patch near their eyes. But why do these mammals sport the markings?
There are various thoughts as to why orcas have these patterns. Their coloring pattern has multiple uses, from camouflage to coordination as they swim. The patterns also help researchers study genetics within a pod.
