Galapagos Giant Tortoise
Scientific Name: Chelonoidis niger
Category: reptile
Brief Description
A massive land-dwelling reptile known for its extreme longevity and large, domed or saddle-backed shell.
Characteristics
Large bony carapace of a dull brown color, thick scaly limbs, and a long neck used to reach vegetation. They can weigh over 900 pounds.
Habitat
Dry lowlands, grassy plains, and moist montane regions.
When to Find It
Active during the day; more active during the transition between the hot/wet season and the cool/dry season.
Conservation Status
Vulnerable to Critically Endangered (varies by subspecies)
Ecological Role
As mega-herbivores, they are ecosystem engineers that shape the vegetation, disperse seeds, and create paths for other smaller animals.
Easily Confused With
Aldabra Giant Tortoise; distinguished by the absence of a nuchal scute (a small scale on the shell above the neck) which the Aldabra species possesses.
Observation Tips
In the wild, they are best observed in the Galapagos Islands; in captivity, maintain a respectful distance and avoid touching the shell as it is sensitive.
Interesting Facts
They are among the longest-lived vertebrates, with some individuals living over 150 years. They can survive up to a year without food or water by breaking down their body fat.
