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 @joelsartore / The Amazonian manatee is the largest mammal in the Amazon rainforest. Manatees are aquatic mammals who spend up to 8 hours a day grazing. Because of how they move in the water, it’s clear why manatee means “fish cow” in Portuguese. While they are graceful swimmers, they are large and slow moving, found in coastal waters and rivers where the greatest risk to their populations are collisions with boats. I ventured to INPA, an aquatic conservation center in Manaus, Brazil for the opportunity to photograph this majestic creature. I used an underwater camera and scuba dived in order to get a closer shot of the manatee. To see more species featured in the Photo Ark, follow me @joelsartore, and to learn more of the Amazonian manatee watch my show, the Photo Ark on @NatGeoWild tonight in the U.S. at 10pm ET.
