Threats to natives: Red-eared slider populations can rival that of the native Florida redbelly turtle (Pseudemys nelsoni) in urban South Florida man-made ponds (Witzell 1999).

Species Account: The red-eared slider is native to the Mississippi River drainages. A subspecies, the yellow-bellied slider (Trachemys scripta scripta), occurs naturally in north Florida. The red-eared slider is the little green turtle that has been sold by the hundreds of millions in dime stores and pet shops throughout the United States, and it is the most commonly exported reptile species, with over 52 million being exported from the United Stages from 1989 through 1997 (Franke and Telecky 2001). As a result, this adaptable species has become established in many areas of the world, including Europe and Japan, where they compete with native turtle species and prey upon fish (summarized by Franke and Telecky 2001). Reproducing populations are present in Florida, and they breed with yellow-bellied sliders in north Florida. Adults may reach a length of 30.5 cm (12 in). Mature males have elongate front claws and may be patternless and almost black colored. Hatchlings are green with numerous lighter and darker lines. The face and limbs are green with numerous yellow stripes, and a broad red stripe is present in the "ear" region. As they age, their color and pattern dulls (Bartlett and Bartlett 1999).

Habitats: Lake, Freshwater river or stream
