Red Eared Invaders

Don’t get us wrong, we love red eared sliders. These friendly southeastern U.S. natives make wonderful pets. But red eared sliders are also one of the most invasive species on Earth, and people are at fault.

Because they are hardy and easy to breed, red eared sliders are the most popular turtle in the pet trade. They can be found everywhere from pet stores to flea markets. Sliders are often sold as quarter-sized babies in tiny plastic tanks. The problem is they don’t stay small.

Big Mama came from the wild in 2019 after being hit by a car. Her shell is 11.5 inches long. She lives in a 150 gallon tank.

Male red eared sliders can reach six inches in shell length. The recommended minimum aquarium size for turtles is ten gallons per one inch of shell, so an adult male slider should have a 60-gallon aquarium. While the little plastic tank was doable, many people lack funds, space, or sufficient interest to properly house a turtle.

And that is just the males. What happens if that baby turtle turns out to be a female, who might grow to resemble half a basketball?

What happens, all too often, is people decide their growing pet turtles should be “free,” and release them into ponds and rivers. There, the sliders who survive (and many do – remember we said they were hardy turtles) take over. All it takes is one male in the mix, as a male may mate with many females, and suddenly there are hundreds of baby sliders. Red eared sliders are aggressive and can outcompete native turtles, like our painted turtles, for food and territory. Sliders also introduce disease into the native turtle populations. Outside of their native range, sliders are known to contribute to the decline of local species.

Thanks to the pet trade, red eared sliders have invaded almost every U.S. state and parts of Canada. They are also exported and are now found in ponds in Europe, Africa, and Asia. And everywhere sliders go, other turtles are in danger.

Keeping red eared sliders out of our native turtle habitats is part of Dancing Turtle’s mission. We take in sliders, recovered from the wild or surrendered, to rehome them or, in the case of the big females, to provide a safe place for them to live out their lives. A long-term goal is a pond enclosed by a fence just for our female sliders.
