The Oldest Living Reptiles on Record: Incredible Tales of Longevity


Reptiles have been around for millions of years, surviving through various changes in their environment. Some species of reptiles have been known to live for an incredibly long time, surpassing the lifespans of many other animals. In this article, we will explore some of the oldest living reptiles on record and their incredible tales of longevity.

Giant Tortoises

Giant tortoises are some of the longest-living reptiles on Earth, with some species living well over 100 years. One of the most famous examples is Jonathan, a Seychelles giant tortoise who is believed to be around 187 years old. Jonathan resides on the island of Saint Helena and is thought to have been born in the early 1830s.

Another well-known giant tortoise is Adwaita, an Aldabra giant tortoise who lived in the Alipore Zoological Gardens in India. Adwaita was estimated to be around 255 years old at the time of his death in 2006, making him one of the oldest recorded tortoises in history.


Tuataras are another group of reptiles known for their exceptional longevity. These ancient creatures are native to New Zealand and have been around for over 200 million years. The oldest living tuatara on record is Henry, who resides at the Southland Museum in Invercargill, New Zealand. Henry is estimated to be over 120 years old.

Alligators and Crocodiles

Alligators and crocodiles are some of the oldest reptile species in existence, with some individuals living for several decades. One of the oldest American alligators on record was Muja, who resided at the Belgrade Zoo in Serbia. Muja was believed to be around 85 years old when he passed away in 2019.

In contrast, a saltwater crocodile named Cassius is believed to be over 110 years old, making him one of the oldest living crocodiles in captivity. Cassius resides at the Marineland Melanesia in Australia and continues to thrive despite his old age.


Reptiles have shown remarkable longevity in the animal kingdom, with some species living for well over a century. From giant tortoises to tuataras, these ancient creatures continue to defy the odds and thrive in their natural habitats. By studying the oldest living reptiles on record, scientists can gain valuable insights into the aging process and how these animals are able to live such long and healthy lives.

As we continue to learn more about the secrets of longevity in reptiles, we can gain a greater appreciation for these incredible creatures and the role they play in our planet’s biodiversity. The stories of the oldest living reptiles serve as a reminder of the resilience and adaptability of these ancient creatures, inspiring us to protect and conserve their habitats for generations to come.
