How many leatherback turtles are left in the wild?

I believe there are around 25-50 left.... they tend to dwell around Africa, and some near the Congo basin. they have survived the extinction of the dinosaurs, and have been around for approximated 150 million year. they can weigh 500-2,000 pounds, and in length (head to tail)4-9 feet long. they are the largest of all sea turtles. they dive very deep, around 4,000 feet. for more info search wikipedia :D
