Giant tortoises are cold-blooded, meaning their internal temperature is affected by how hot or cold their environment is. They spend their mornings basking in the sun to absorb heat, and then spend the rest of the day grazing and resting. Some types of giant tortoise prefer to move in large groups, while others are more solitary.
They are herbivores, eating a variety of plants including leaves, grass, cacti, berries and other fruit, and more.
Tortoises usually breed during the hotter months, and then move into nesting zones in the lower areas of their island homes in the cooler months to lay their eggs.
Females dig holes with their back legs and deposit eggs before covering the holes back up. The eggs will incubate for up to 175 days before hatching.
The name “giant tortoise” refers to several species of large land turtle, most prominently two species complexes: the Galapagos giant tortoises of the Galapagos Islands in the Pacific Ocean, and the Seychelles-Aldabra giant tortoises of the Seychelles Islands in the Indian Ocean.
They can weigh almost a thousand pounds and can grow over four feet long. They are slow-moving creatures that dwell mainly on small islands, and their large size is due to a phenomenon called “island gigantism” in which species isolated on small islands can grow much bigger than other species living on continental land masses.
Giant tortoises are some of the world’s longest-living animals, able to live over 100 years on average. Some can live to be much older, potentially well over 200 years.
The giant tortoise was originally believed to be a single species. However, it was later discovered that those of the Galapagos were different species than those of the Seychelles, and that within those different species were many additional sub-divided populations. There are believed to be14 or 15 subspecies of the Galapagos tortoise, and four subspecies of the Aldabra giant tortoise.
The Aldabra giant tortoise is believed to be a Vulnerable species, while several subspecies of the Galapagos tortoise are Vulnerable, Endangered, Critically Endangered, or completely Extinct. The last known Abington Island Tortoise, named Lonesome George, died in 2012.
Galapagos tortoises were used as food for whaling vessels sailing in the Pacific Ocean, and many tortoises were exported to California to use as food during the Gold Rush of 1849. As settlers moved to the Galapagos Islands, habitat clearance for cattle further harmed the tortoise populations.
The Aldabra tortoise, on the other hand, has benefited from a targeted conservation effort that goes back to the 1800s. A preserve was established back then to protect the tortoises and their habitat.
