By the first quarter of the 21st century, this species has spread widely across the waters of Europe and Southeast Asia, and is also found in the Urals and Siberia.

Two states have completely banned the sale of these turtles. Many states also have passed legislation to control the possession and release of pond sliders. Not uncommonly, they also escape.Ĭonservationists have warned owners of turtles to not release them into the wild.
Turtles raised in captivity are often released because they become too much to handle or grow bigger than expected. Turtles that were raised in captivity can develop diseases that are unfamiliar to native species, which can be harmful. When basking, pond sliders commonly bask on birds' nests, thereby killing the eggs. Eventually, they bully many native species out of basking sites, where sunlight (and warmth) is available for the species. These turtles often compete with native species for food, habitat, and other resources. In the 1950s, millions of turtles were being farmed and shipped abroad as part of the pet trade. In the 1900s, many pond sliders were captured for sale. scripta in New York, USA, where they are invasive species Midwestern United States to northern Mexico Pond sliders are native to the south-central and southeastern United States and northern Mexico. Groups of sliders, sometimes quite large, as well as many other types of less abundant freshwater turtles, are often seen basking and sunning on logs, branches, and vegetation at or even well above the water's surface, but they readily and quickly scramble if they sense danger, shooting back in and darting away to safety underwater. The origin of the name slider stems from the behavior of these turtles when startled. Their lifespans range from 20 to 50 years. For determining an adult slider's sex, males typically have much longer front claws than adult females, while females usually have shorter, more slender tails than males.

Some sliders become almost black with few visible markings.

Hatchling and juvenile pond sliders have a green upper shell ( carapace), yellow bottom shell ( plastron), and green and yellow stripes and markings on their skin. elegans), which is popular in the pet trade and has been introduced to other parts of the world by people releasing it to the wild.
