96-inch Leatherback Turtle

Leatherbacks are the largest turtles on Earth, growing up to seven feet long and exceeding 2,000 pounds. These reptilian relics are the only remaining representatives of a family of turtles that traces its evolutionary roots back more than 100 million years. Once prevalent in every ocean except the Arctic and Antarctic, the leatherback population is rapidly declining in many parts of the world. (NatGeo)
