What You'll Learn
Turtles live longer than most pets
Turtles are known to live longer than many other pets. The average lifespan of a turtle or tortoise is highly dependent on the species. Some species may only live 10 to 20 years in captivity, while others can live up to 150 years. In general, most turtle and tortoise species can live well into their 50s if provided appropriate care.
Long Lives
Several common species of pet water turtles can live into their 40s. Larger turtles and tortoises can live extremely long lives. The smaller species that are more common as pets may survive several decades. There are many records of tortoises that have lived nearly 200 years or even more.
The oldest living land animal on Earth, and the oldest turtle in recorded history, is Jonathan, a Seychelles giant tortoise. He turned 191 years old in 2023 and may be older, as experts are unsure of his exact birth date. He was born around 1832 in Seychelles before being brought to St Helena Island in 1882. The average life expectancy for his species is 150 years.
Longevity Factors
Several factors may play a role in the longevity of turtles. One explanation is that they have a slow metabolism and a slower heart rate compared to other animals. Researchers have also found that they have a slower rate of ageing, start reproducing at an older age, and have protective shells, all of which may contribute to their long lives.
Care Considerations
Turtles and tortoises require a considerable time commitment to ensure appropriate care throughout their lives. They can be challenging to care for, and improper care can lead to illness and extremely short lifespans. It is important to research each species and work with a reptile veterinarian to meet their specific needs.
Tortoises and turtles require specific diets, environments, and care to thrive. For example, most tortoises are herbivores, requiring a multitude of grass and grass hays, while most turtles are omnivores, eating plants and animal protein. All require calcium supplementation.
Tortoises require shelter and large pens and typically do best when kept outdoors. Aquatic and semiaquatic turtles need large areas to swim, bask, and hunt, with good filtration, frequent water changes, and cleaning to maintain their health.

Diet and environment affect lifespan
A turtle's diet and environment have a significant impact on its lifespan. In the wild, turtles have to search for food while evading predators, and they lack access to veterinary care. As a result, turtles in captivity typically live longer than those in the wild. However, improper care, such as an inadequate diet and unsuitable environment, can lead to sick turtles with extremely short lifespans.
Turtles have specific dietary requirements that vary depending on the species. Most turtles are omnivores, consuming both plants and animal protein. However, some species, like the softshell turtle, primarily feed on fish and meat, while others, like the red-eared slider, eat a mix of insects, fish, and vegetables. A balanced diet that meets the nutritional needs of the specific turtle species is crucial for its overall health and longevity.
Vitamin A and calcium deficiencies are common in captive turtles due to improper lighting and diet. Abscesses, shell infections, respiratory infections, and parasites are all health issues that can affect turtles kept as pets. These issues can be mitigated by providing a clean and spacious enclosure, maintaining proper temperature and humidity levels, and ensuring access to clean water.
For example, aquatic and semi-aquatic turtles require large areas to swim, bask, and hunt. The quality of their tank water is critical, as they spend most of their time in it. Regular water changes, good filtration, cleaning, and water testing are essential for maintaining the health of these turtles. Unclean water can lead to shell erosion, ulceration, dermatitis, infections, and even death.
Additionally, ultraviolet (UV) lighting is crucial for most turtles, including aquatic turtles, as it allows for proper calcium metabolism. Access to UV light can help prevent calcium deficiencies, which are often secondary to Vitamin D deficiency and can cause soft shells and poor growth.
By providing a suitable environment, proper diet, and veterinary care, turtle owners can significantly impact their pet's lifespan, ensuring they live a long, happy, and healthy life.

Turtles can live longer in captivity
Turtles and tortoises are among the longest-living species that can be kept as pets. While they can be fantastic pets, they require a significant amount of commitment to ensure proper care throughout their lives. By providing this care and commitment, you can establish a genuine, lifelong companionship with these fascinating creatures.
Lifespan in Captivity vs. in the Wild
Typically, most turtles and tortoises live longer in captivity than in the wild. In the wild, they have to find their own food while trying to evade predators, and they don't have access to regular veterinary care. On the other hand, if they are kept as pets, it is important to provide them with the proper environment and a nutrient-rich diet. Improper care, including a nutrient-deficient diet and an inappropriate environment, can often make them sick and lead to extremely short lifespans.
Factors Affecting Lifespan
The lifespan of a turtle or tortoise depends on its species, diet, and other aspects of its environment. Larger species of turtles and tortoises usually outlive their smaller counterparts. However, even smaller turtles can live up to two or three decades, and some can even live longer with proper care.
Improving Your Turtle's Lifespan
With proper research, commitment, and an established relationship with a veterinarian, turtles and tortoises can make excellent family pets. Here are some tips to improve your turtle's lifespan:
- Provide a clean and spacious enclosure with the proper temperature, humidity, and lighting (including UVA and UVB lighting).
- Feed your turtle a healthy and species-appropriate diet, including a mix of commercial turtle pellets and fresh foods such as insects, fish, and vegetables.
- Ensure regular veterinary care and take your turtle for routine annual exams.
- Keep the water in your turtle's tank clean and maintain good water quality.
- Protect your turtle from predators and environmental threats, especially if they live outdoors.

Some turtles can live for over 100 years
Tortoises and turtles are among the longest-living species that can be kept as pets. They are part of the reptile group known as chelonians. While the words "turtle" and "tortoise" are often used interchangeably, turtles typically refer to species that live on land and in water, while tortoises live only on land.
The lifespan of a tortoise or turtle depends on its species, diet, and care. Generally, most species can live well into their 50s if provided with appropriate care. However, some tortoises and turtles can live much longer, with lifespans of up to 150 years or more.
Longevity of Turtles and Tortoises
The average lifespan of a turtle or tortoise can vary significantly depending on the species. Some species may only live 10 to 20 years in captivity, while others can reach ages of 100 to 150 years or more. Larger turtles and tortoises tend to live longer than their smaller counterparts.
Factors Affecting Lifespan
Several factors contribute to the long lives of chelonians. One explanation is their slow metabolism and slower heart rate compared to other animals. Researchers have also found that they have a slower rate of ageing, start reproducing at an older age, and have protective shells, all of which may extend their lifespan.
Examples of Long-Living Turtles and Tortoises
Some well-known examples of long-lived tortoises include Adwaita, an Aldabra giant tortoise that reportedly lived to 255 years old, and Jonathan, a Seychelles giant tortoise that lived to be around 191 years old.
Leopard tortoises and Greek tortoises are known to have lifespans of 100 years or more. Other species with estimated lifespans of up to 100 years include Horsfield's (Russian) tortoise, Mediterranean tortoise, Hermann's tortoise, and the spotted turtle.
Enhancing Lifespan
Providing proper care and creating an ideal environment for your turtle or tortoise can significantly enhance their lifespan. It is crucial to work closely with a reptile veterinarian to meet their specific needs, such as appropriate diet, temperature, humidity, vitamin supplementation, and housing size.
Tortoises, being primarily herbivores, require a diet rich in grass, grass hays, and greens. Turtles, on the other hand, are mostly omnivores, and their diet should include a mix of plants and animal protein.
Ensuring good water quality is essential for aquatic and semi-aquatic turtles, as they spend most of their time in the water. Regular water changes, water testing, good filtration, and cleaning are necessary to prevent shell erosion, ulceration, and other health issues.
Planning for Longevity
When considering a turtle or tortoise as a pet, it is essential to recognise that their long lifespans require a significant commitment. Proper care and research are necessary to provide them with a healthy and happy life. Additionally, it is important to plan for their future, including identifying a family member or friend who can care for them if you are no longer able to do so.

Turtles are susceptible to certain diseases
Turtles are known to live long lives, with some species of tortoises living up to 100 years or more. While turtles can make excellent pets, their longevity means that owning one is a long-term commitment.
To ensure your turtle lives a long and healthy life, it's important to be aware of the typical diseases that can affect these reptiles. Here are some of the most common diseases and conditions that turtles are susceptible to:
- Metabolic Bone Disease (MBD): MBD is caused by an imbalance of calcium and phosphorus in a turtle's diet, a lack of adequate ultraviolet (UV) light, or a combination of both. Signs of MBD include a misshapen shell and deformed bones in the legs. Turtles with MBD grow slowly and often do not reach their full adult size.
- Vitamin A Deficiency (Hypovitaminosis A): This condition occurs when turtles are fed an inappropriate diet, such as iceberg lettuce, an all-meat diet, or poor-quality commercial food. Vitamin A deficiency affects the epidermis, mucus-producing glands, and membranes in the mouth, eyes, kidneys, and upper respiratory tract. Symptoms include lack of appetite, lethargy, swelling of the eyelids, kidney failure, and chronic respiratory infections.
- Respiratory Tract Infections: These infections are often caused by bacteria and are secondary to vitamin A deficiency. Turtles with respiratory infections may have excess mucus in their mouths, nasal discharge, lethargy, loss of appetite, wheezing, and open-mouth breathing. If the infection spreads to the lungs, the turtle may develop pneumonia.
- Abscesses: These are infected, pus-filled swellings that can appear anywhere on the turtle's body. They often develop in the ears or oral cavity, causing large swellings behind the eyes or on the roof of the mouth. Abscesses are also associated with vitamin A deficiency.
- Shell Infections: Also known as shell rot, these infections are caused by bacteria, fungi, or parasites. They are often secondary to trauma, burns, or bites. Shell infections can penetrate deep into the shell layers, causing ulcers and pitting.
- Parasites: Gastrointestinal parasites, such as roundworms and protozoa, are common in turtles. Parasitic infections may not cause any noticeable symptoms, but severe infections can lead to diarrhoea or weight loss. Regular faecal screenings by a veterinarian can help detect and treat these infections.
By being aware of these common diseases and providing proper care, nutrition, and veterinary attention, you can help your turtle live a long and healthy life.
