ナショナルジオグラフィックさんのインスタグラム動画 - (ナショナルジオグラフィックInstagram)「Video by @bertiegregory A green sea turtle dives after breathing at the surface. When resting underwater, these turtles can hold their breath for more than four hours. These turtles are big—they can weigh over 700 lbs (300kg), grow to five feet (1.5m) long, and live more than 80 years. They get their name not from the color of their shell but the color of their skin. The two fish hitching a ride are called remoras.
