how big is a leatherback turtle
The largest of the sea turtles, the leatherback can reach over 1.8 m (6 ft) in length and 680 kg (1,500 lb) in weight. During their long migrations, leatherbacks regularly dive to depths greater than 1,000 m (3,281 ft) in search of gelatinous zooplankton to eat. The leatherback is rapidly declining in many areas of the world.
