Galapagos Giant Tortoise (Chelonoidis niger)
The Galápagos tortoise or Galápagos giant tortoise (Chelonoidis niger) is a very large species of tortoise in the genus Chelonoidis (which also contains three smaller species from mainland South America). It is the largest living species of tortoise, and can weigh up to 417 kg (919 lb). They are also the largest extant terrestrial cold-blooded animals (ectotherms).
With lifespans in the wild of over 100 years, it is one of the longest-lived vertebrates. Captive Galapagos tortoises can live up to 177 years. For example, a captive individual, Harriet, lived for at least 175 years. Spanish explorers, who discovered the islands in the 16th century, named them after the Spanish galápago, meaning “tortoise”
