Red-eared Sliderミシシッピアカミミガメ
Trachemys scriptaLC— Least Concern
The red-eared slider is a freshwater turtle native to the central and southern United States, easily recognized by the red stripe behind each eye. Popularized worldwide by the pet trade, it has been released into the wild across six continents and is now considered one of the world's most invasive turtle species, including in Japan, where roughly a million were imported annually in the mid-1990s. Omnivorous and adaptable, juveniles favor animal prey while adults shift toward a more plant-based diet.

Species Data
Did You Know?
- In the mid-1990s, roughly one million individuals were imported into Japan annually, and this pet-trade popularity later fueled widespread releases into the wild. Source
- Sex is determined by incubation temperature; experiments found clutches incubated at 22.5-27°C produced only males, while 30°C produced only females. Source
- Widespread release of unwanted pets has established populations on six continents, leading conservationists to describe it as the world's most invasive turtle species. Source

FAQ
- Why is the red-eared slider considered invasive?
- Decades of pet-trade popularity led to widespread releases of unwanted turtles into the wild, establishing populations on six continents and making it one of the most invasive turtle species in the world. Source
- How is the sex of a red-eared slider determined?
- Like many turtles, sex depends on the incubation temperature of the egg; experiments found that lower temperatures around 22.5-27°C produced all-male clutches, while about 30°C produced all-female clutches. Source
- How long do red-eared sliders live?
- They commonly live 20 to 30 years, and some well-cared-for individuals have lived more than 40 years. Source
