The red-eared turtle (Trachemys scripta elegans) is one of the most popular pet turtles in North America. This common semi-aquatic turtle is native to the American Midwest and northern Mexico, but due to free reintroduction and breeding, it has become one of the most invasive turtles in the world. This turtle's habitat is mainly still warm waters, such as ponds, lakes, swamps and slow-flowing rivers, which are suitable for the life and reproduction of red-eared turtles.
The red-eared slider's native area is located near the Mississippi River and the Gulf of Mexico, which has a warm climate. They are commonly found in still waters, especially areas with easy access to shore, such as rocks or tree trunks, where they can sunbathe in the sun. This turtle likes to gather together and can often be seen basking in the sun together.
Red-eared turtles require an abundance of aquatic plants as these are the main food of mature turtles, despite their omnivorous nature.
The red-eared slider has become an invasive species in many places, negatively impacting local ecosystems. These turtles' early maturation, high reproductive rate, and large size give them an advantage when competing with native species. Not only do they spread diseases, but they also crowd out local turtles, affecting their survival and reproduction.
In Western Australia, red-eared turtles are considered a critical threat to native turtles because they demonstrate significant advantages in competition for food and habitat.
Characteristics of the natural habitat shape the red-eared slider's lifestyle. These turtles usually live near water and like to stay in the sun to regulate their body temperature. When water temperatures drop below 10 °C (50 °F), they enter a state called "latent sleep" rather than true hibernation, allowing them to survive the cold season.
The red-eared slider has been introduced in large numbers around the world, making it one of the invasive species farthest from its native range. Especially in areas like Australia and Europe, they pose a significant threat to local ecosystems. Human activities have had a major impact on their survival, including habitat destruction and overfishing.
Due to their ease of care and relatively low price, red-eared turtles have become one of the most popular pets in the world. However, the environments these turtles live in homes are often very different from their natural habitats, which can cause their health and lifespan to suffer.
The survival process of the red-eared slider reflects how organisms in nature adapt to the environment. However, as an overbred and introduced species, they have also become disruptors of ecological balance in certain areas. Have you ever wondered, when appreciating these cute pets, have we considered enough factors for their future?
