The red-eared slider is a semi-aquatic freshwater turtle, scientifically named *Trachemys scripta elegans*, and a subspecies of the pond slider in the family Emydidae.

In Canada, it is considered an invasive species.

Description

The red-eared slider is a semiaquatic turtle with a red or orange mark behind each eye and a freshwater lifestyle. It belongs to the turtle family Emydidae and is a subspecies of the pond slider.

Range and habitat

The species is native to the southern and central United States and northern Mexico. It lives in ponds, rivers, lakes, marshes, and other freshwater habitats, and has established invasive populations in many other parts of the world.

Pet trade and invasiveness

Red-eared sliders are widely kept as pets and are among the most traded turtles globally. Releases from captivity have helped spread the species far beyond its native range, where it can compete with native turtles and other wildlife. In Canada, the species has been introduced mainly through the pet trade and pet releases.

Ecology and identification

The red mark behind each eye is the most widely used identification feature. The species is well known in North American wildlife references and invasive-species programs because of its broad distribution and ecological impact.
