giant tortoise

Massive shelled reptile

Giant tortoises are the largest living tortoises, found primarily in the Galápagos Islands and Seychelles.

They can weigh over 400 pounds and live well past 100 years—among the longest-lived vertebrates.

Their slow metabolism and island habitats with few predators allowed them to grow to remarkable size: The giant tortoise lumbered across the volcanic rock.
