Giant turtles reappear after 150 years of extinction

On January 9, 2012, scientists reported that the giant turtle, Chelonoidis elephantopus, was "extinct" 150 years ago to reappear on the Galápagos Islands in the Pacific Ocean.

This turtle is closely related to the Chelonoidis becki turtle living in the islands, about 200 miles from Floreana Island (322km). The last Chelonoidis elephantopus turtle was seen in Floreana Island about 150 years ago.

It is known as a giant turtle because adults can weigh nearly 900 pounds and are nearly 6 feet long.

Through genetic analysis, researchers estimate that at least 38 C. Elephantopus still live in the Galápagos Islands. And there may be more. Scientists are still not sure how this turtle came to the Galápagos Islands. It is also possible that it was brought from Floreana Island to food here.
