Photograph by @Thomas Peschak Cape Fur seals often porpoise like dolphins on the way to their offshore feeding grounds. Close to shore they are vulnerable to being surprised by great white sharks from below. Porpoising is believed to confuse predators and increase speed all while still being able to maintain a vigilant underwater watch for danger. @ナショナルジオグラフィック @thephotosociety @natgeocreative
