Green turtle

Green turtle. Green turtle (Chelonia mydas) swimming beside a coral reef. This turtle uses its powerful paddle-like front limbs to propel itself through the water. Its name derives from the colour of its flesh. The green turtle is one of the largest turtles, growing up to 150 centimetres in length. Found in all warm tropical waters, C. mydas is almost completely aquatic. Only the female ever leaves the water: she does so to nest, returning to the beach where she was born to lay her eggs. Photographed off Palau Sipadan, Malaysia
