What Is a Red-Eared Slider and How Long Does It Live?

Check out this answer from Consensus:

Red-eared sliders are resilient turtles with a potential lifespan of several decades, especially when provided with optimal care. Their health and longevity are influenced by environmental conditions and exposure to stressors, highlighting the importance of proper habitat management.

The red-eared slider (Trachemys scripta elegans) is a semi-aquatic turtle native to the southern United States. It is easily recognizable by the distinctive red stripe around its ears, which gives it its name. These turtles are popular pets due to their relatively small size and ease of care. They are known for their adaptability to various environments, which has also led to them becoming an invasive species in some areas outside their native range1 2.

Lifespan of Red-Eared Sliders

Red-eared sliders have a relatively long lifespan compared to other reptiles. In the wild, they can live for about 20 to 30 years, while in captivity, with proper care, they can live even longer, sometimes reaching up to 40 years. Their longevity is influenced by factors such as diet, habitat conditions, and overall health management. Proper care includes maintaining clean water, providing a balanced diet, and ensuring adequate basking areas and UVB lighting1 2.

Factors Affecting Health and Longevity

Several factors can impact the health and longevity of red-eared sliders. Environmental conditions, such as temperature and water quality, play a crucial role. For instance, temperature during incubation can affect the antioxidant capacity of hatchlings, which is important for their long-term health and survival2. Additionally, exposure to environmental stressors like herbicides and pathogens such as ranavirus can affect their growth and survival rates, although some studies have shown that herbicide exposure alone may not significantly impact their health1.
