Facts about the real animal.

The red-eared slider is a subspecies of the pond slider, Trachemys scripta.

01

Its original home is the southern United States to northeastern Mexico. Today it can also be seen in waters almost all over Japan.

02

Orange-red patches stand out on both sides of its head. Its toes are webbed, which makes them good for swimming.

03

When young it eats mostly animals, but as it grows up it becomes an omnivore that eats both plants and animals.

How the Red-eared slider lives

It is active during the day and basks in the sun. Mating takes place in spring and autumn. A male courts a female by vibrating his elongated claws in front of her. The female digs a hole in the ground and lays eggs in it.

Each dot marks a place with observations or specimens shared on GBIF. Some records are of animals that strayed or were brought by people, so the dots are not always where the animal lives.

Sources and how we check

We check each fact against its source. The illustrations simplify how the real animal looks.

The classification (class, order, family, genus) follows Wikidata records, checked against GBIF. Classifications can change as research goes on.

The basic data are the values given in each source. They vary with how the animal is measured, whether it is male or female, and whether it lives in the wild or in captivity.
