ナショナルジオグラフィックさんのインスタグラム写真 - (ナショナルジオグラフィックInstagram)「Photo by Cristina Mittermeier @mitty | A friend told me she can't grasp which part of the animal she's looking at in a picture like this. Sometimes I take for granted the things I know—and I fail to explain them to those that might be seeing an animal for the first time! What we see here are four humpback whales feeding together. Their mouths are open and their throat pleats distended to accommodate the large volume of water they must displace in order to filter fish and krill through their baleen. It is an incredible spectacle to watch when these large animals emerge from the water with such force. I can only imagine what goes on underwater, but it must be amazing. Humpback whales were almost completely wiped out by whaling. They made a fabulous comeback when they received protection by mechanisms such as the Endangered Species Act, a crucial piece of legislation that has recently become endangered itself.
