The
Red-eared Slider is a semi-aquatic turtle native to Southern United States but can be found throughout the country East of the Rockies. It is the most popular pet turtle in the United States.
Red-eared Sliders are in the same family as
Painted Turtles and can often be observed basking in the sun together. They are slightly larger than their cousins and can be easily identified by the distinctive red mark around their ears.
When the
Teenage Mutant Ninja Turtles were revealed to be specimens of the
Red-eared Slider, there was a craze to keep them as pets in some parts of the world. The
pet trade, release of unwanted turtles into the wild and the high adaptability of the species has led to the
Red-eared Slider appearing in the
100 of the World's Worst Invasive Alien Species list (currently #93).
At the
John Heinz National Wildlife Refuge where this photograph was taken, the invasive
Red-eared Sliders are in competition with the native
Northern Red-bellied Cooter, which is listed as a threatened species in Pennsylvania.
