How Long Does a Tortoise Live?

Tortoises are renowned for their impressive longevity, often living for several decades and even surpassing a century in some cases. 

  • On average, a tortoise will live up to 250 years. This is especially true for species such as giant tortoises. 
  • Jonathan, a Seychelles giant tortoise, is the world’s oldest known living land animal. Jonathan was born around 1832 on the South Atlantic island of St. Helena. He is believed to be over 190 years old at the time of writing.

Jonathan’s longevity can be attributed to several factors, including his species (Aldabra giant tortoise) and the island’s favorable environmental conditions. He has become an icon of longevity and a beloved resident of St. Helena, winning the hearts of locals and visitors.

  • Adwaita, another remarkable tortoise, deserves special mention for his exceptionally long lifespan. Adwaita was an Aldabra giant tortoise who lived at the Alipore Zoological Gardens in Kolkata, India. 

The zoo reportedly acquired him in the early 1870s, and died in 2006, making him approximately 255 years old. While his exact age is unknown, Adwaita’s longevity demonstrates the potential lifespan of tortoises as well as the importance of proper care.

These extraordinary examples of tortoise longevity show how these animals can be cherished companions for generations. It also emphasizes the importance of providing suitable habitats, balanced diets, and appropriate healthcare to ensure their well-being and extend their lifespans.

Understanding the typical lifespan of different tortoise species allows us to appreciate the commitment required when welcoming one into our lives. Here is a video of a 104-year-old tortoise.

How Do Tortoises Live So Long?

While various factors contribute to their extended lifespans, several key factors significantly influence their longevity.

Slow Metabolism and Growth

Tortoises have a remarkably slow metabolic rate when compared to many other animals. Their slow metabolism allows them to conserve energy and maintain bodily functions at a slower rate. 

This slower metabolic rate contributes to their slow growth, ensuring their bodies age slower than faster-growing animals.

Species-Specific Traits

The life expectancy of various tortoise species varies. The Galapagos tortoise (Geochelone nigra) and Aldabra tortoise (Aldabrachelys gigantea), for example, are known for their exceptional longevity. These massive tortoises can live for over a century and have even been reported to live for 150 years or more. 

How Do Tortoises Live So Long

Limited Predation and Disease

Unlike many other animals, tortoises have few natural predators in their environments. Their protective shells and slow movement make them less vulnerable to predation. 

Tortoises have developed strong immune systems, and their low body temperatures may make them less susceptible to certain diseases.

Delayed Reproduction 

Tortoises frequently exhibit delayed sexual maturity, with some species taking several years to reach reproductive age. This delayed reproduction allows them to devote more energy to growth, development, and overall health before investing in reproductive efforts. 

DNA or Genetics

Some individuals, such as giant tortoises, may inherit genes that promote longevity. And others may be more susceptible to health issues or have a shorter lifespan due to their genetic makeup. However, compared to other animals, the influence of genetics on tortoise lifespan is less well understood.

Factors such as climate, availability of food, and exposure to natural hazards can vary significantly based on the region. Tortoises in regions with favorable environmental conditions and fewer natural threats may experience longer lifespans than those in less favorable areas.

For example, species that live in remote locations, such as the Galapagos Islands, will be less affected by human pollution and interference. This enables them to reach their full potential.


While there is not enough research, there is a correlation between an animal’s size and lifespan, which is true for tortoises. The largest specimens of these reptiles have the longest lives. As a result, it is unlikely that a small pet tortoise will live for centuries.

Nonetheless, factors such as a good habitat and access to abundant food also weigh in here. For example, a large tortoise will not thrive or live longer if kept in a filthy environment teeming with bacteria.
