About
The Galápagos giant tortoise is the largest living species of tortoise, native to the Galápagos Islands. Modern Galápagos tortoises can weigh up to 417 kg (919 lb) and measure 1.87 m (6 ft 2 in) in length. They are long-lived, with a lifespan of over 100 years in the wild. Charles Darwin's observations of these tortoises during the voyage of the Beagle contributed to his theory of evolution by natural selection.
Fun Fact
Galápagos giant tortoises can survive up to a year without food or water, which is why sailors historically loaded them onto ships as a living food supply on long voyages — inadvertently decimating populations.
