FUN FACTS
- Mississippi map turtles are named for the intricate patterns on their shells, which can vary significantly among individuals, making each turtle unique
- They are also known for their basking behavior, often seen sunning themselves on logs or rocks, which is essential for their thermoregulation and overall health.|These turtles play an important role in their ecosystems by helping to control populations of aquatic invertebrates and contributing to the nutrient cycle in their habitats
- Their presence indicates a healthy aquatic environment, making them valuable indicators of ecosystem health
