We’ve covered the sea, so let’s look at the world’s longest-living animals who roam around on land, like our old pal Jonathan, the Seychelles giant tortoise.
1. Galápagos Tortoises
These tortoises are renowned for their long lifespans, with many individuals living over 100 years and some reported to be more than 150 years old. Their slow metabolism and island lifestyle are critical factors in their extended lifespans.
2. Tuatara
This reptile, indigenous to New Zealand, stands out for its potential to live over 100 years, with some unverified claims of tuataras reaching up to 200 years.
The reptile’s unique biological characteristics, including a third “parietal” eye on its forehead and specific physiological and metabolic traits, contribute to its longevity.
3. Asian Elephants
In the wild, Asian elephants can live 60 to 70 years, but under human care in captivity, they can surpass 80 years. Their size and social structure — along with human protection from predators and provision of medical care — play roles in their longevity.
4. Macaws and Parrots
Known for their vivid colors and intelligence, some species of macaws and parrots, like the hyacinth macaw and grey parrots, can live beyond 50 years in the wild and up to 80 years in captivity, making them among the longest-lived bird species.
