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 Paul Nicklen @PaulNicklen | This curious bowhead whale came to greet me while I was diving in the Canadian Arctic. As I hovered in the frigid water along the north coast of Baffin Island, this whale came so close that it actually pushed me with its chin. Able to live over 200 years, bowhead whales have the longest life span of any mammal on Earth. Their populations were once almost wiped out by whaling, and they now face the new threat of a warming Arctic. Higher temperatures are rapidly melting sea ice, on which they rely for copepods, their main food source. #FollowMe at @PaulNicklen and explore my feed for more photos of whales. #bowhead #Arctic #ocean #underwaterphotography」5月21日 12時33分
