Sharks And Dolphins Battle
There’s a good chance the friendly dolphins came to Walker’s aid because of a long-standing rivalry between them and humans.
Every day, dolphins and sharks engage in fierce combat in the water. Unlike sharks, which target dolphin calves and those that become away from the pod, dolphins always cruise in groups.
Even the fearsome great white shark hesitates to take on a well-coordinated pod of dolphins. A shark might be knocked unconscious by the dolphins’ tails alone if they band together.
