…it"s World Sea Turtle Day! The gentle giant seen here doing the wave was snapped mid-dive, headed to the seafloor near the Great Barrier Reef to munch some marine grass. The green sea turtle is among the larger of the seven sea turtle species, with some individuals reaching 5 feet in length and weighing 700 pounds. They live throughout the world"s subtropical waters, and like other sea turtles, they migrate long distances for food. Despite all that traveling, they return to hatch their eggs on the same select nesting beaches where they were born.
