Quick answer
The Galápagos tortoise is the largest living tortoise and one of the longest-lived land animals, found only on the Galápagos Islands. Large males can weigh more than 250 kg (550 lb), and individuals routinely live over 100 years. These slow-moving herbivores were central to Charles Darwin's thinking on evolution and are now a conservation icon.

Biology
Galápagos Tortoise (Chelonoidis niger) is classified as Reptile with conservation status Vulnerable. Typical weight Up to 250 kg (550 lb) or more; lifespan around Over 100 years.
Ecology
Diet: Herbivore. Habitat: Volcanic islands, grasslands, and scrub. Movement and social systems reflect those pressures.
People and this species
Learn before you travel or keep related pets. Wild individuals are not toys; captive care needs species-specific husbandry.

Behavior and longevity
Galápagos tortoises live life slowly, spending much of the day basking, grazing, and resting, and they can survive long periods without food or water by storing both in their bodies. They are among the longest-lived vertebrates, with many individuals passing 100 years and some reaching well beyond that. Their unhurried pace and large size give them few natural enemies as adults.
Diet and feeding
These tortoises are herbivores that eat grasses, leaves, cactus pads, and fruit. They can go for long stretches between meals and obtain much of their water from dew and plant moisture, an adaptation to the islands' dry seasons. Different islands favor different feeding styles, reflected in the shape of each population's shell.
Habitat and range
The Galápagos tortoise lives only on the Galápagos Islands, a volcanic archipelago off the coast of Ecuador. Populations are spread across several islands, ranging from lush highland meadows to arid lowland scrub. Saddle-backed shells evolved on drier islands to let tortoises stretch upward for taller vegetation, while domed shells are typical of wetter highlands.
Conservation
Hunting by sailors and introduced animals such as goats, rats, and pigs devastated tortoise numbers after European arrival, and several populations were lost. Today the species is listed as Vulnerable, and intensive conservation, including captive breeding and the removal of invasive species, has helped some populations recover. The Galápagos tortoise remains a global symbol of island conservation.
Research notes
Figures for galápagos tortoises (Chelonoidis niger) come from field studies, museum records, and conservation assessments that do not always agree on exact averages. Prefer ranges over single-point claims, and check whether a source describes wild, captive, or mixed populations.
Practical takeaways
If you encounter galápagos tortoises in the wild, prioritise distance and local guidance. If you care for related domestic or captive animals, match diet and housing to species needs rather than generic pet advice. Share accurate status information (Vulnerable) when discussing conservation.
