Quick Answer. The sheer size of a fully grown humpback whale dissuades all but the most aggressive sea predators from attacking them. In addition, whales typically swim in large groups called pods to protect smaller, weaker whales and youth. Mothers with calves swimming within a pod are accompanied by escort whales, which follow along slightly outside the pod to protect against aggression from competing humpback groups.
