National Geographic Travelさんのインスタグラム写真 - (National Geographic TravelInstagram)「Photo by @CristinaMittermeier | A group of gentoo penguins rockets up from the deep as they head towards the shore. Gentoo penguins have powerful flippers, allowing them to travel up to 22 miles an hour underwater, the fastest speed of any diving bird. This split-shot reveals the excitement, happening just below the clear blue waves off this SubAntarctic coast as the penguins hurry back to the colony to feed their chicks while avoiding the ever-present southern sea lions waiting to ambush them. #FollowMe at @CristinaMittermeier for more photos of penguins. #gentoo #underwaterphotography #wildlife #nature」4月22日 6時58分
