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 @paulnicklen | A leopard seal patrols a slab of sea ice, hoping for one of the many young Adélie penguins to slip up and fall into the icy depths of the Antarctic waters. Penguin chicks are extremely vulnerable during their first few times in the water, as they are inexperienced and have not yet refined their swimming speed and strategies. Leopard seals take full advantage of this and coordinate their migration to coincide with the specific time that penguin chicks journey from their colony to the sea. #FollowMe at @PaulNicklen for more photos from #Antarctica. #penguin #leopardseal #nature #wildlife」4月4日 3時02分
