19-10-2025 TAVERNES PLAYA, VALENCIA - POND SLIDER TERRAPIN (Trachemys scripta)

The pond slider (Trachemys scripta) is a species of common, medium-sized, semiaquatic turtle. Three subspecies are described, the most recognizable of which is the red-eared slider (T. s. elegans), which is popular in the pet trade and has been introduced to other parts of the world by people releasing it to the wild. Hatchling and juvenile pond sliders have a green upper shell (carapace), yellow bottom shell (plastron), and green and yellow stripes and markings on their skin. These patterns and colors in the skin and shell fade with age until the carapace is a muted olive green to brown and the plastron is a dull yellow or darker. Some sliders become almost black with few visible markings. The carapace is oval with a bit of rounding and a central crest with knobs, but these features soften and fade with age, adults being smoother and flatter. For determining an adult slider's sex, males typically have much longer front claws than adult females, while females usually have shorter, more slender tails than males. Their lifespans range from 20 to 50 years.

1-6-2025 MARJAL DEL BORRONS, GANDIA - POND SLIDER TERRAPIN (Trachemys scripta)

The pond slider (Trachemys scripta) is a species of common, medium-sized, semiaquatic turtle. Three subspecies are described,[2] the most recognizable of which is the red-eared slider (T. s. elegans), which is popular in the pet trade and has been introduced to other parts of the world by people releasing it to the wild. Hatchling and juvenile pond sliders have a green upper shell (carapace), yellow bottom shell (plastron), and green and yellow stripes and markings on their skin. These patterns and colors in the skin and shell fade with age until the carapace is a muted olive green to brown and the plastron is a dull yellow or darker. Some sliders become almost black with few visible markings. The carapace is oval with a bit of rounding and a central crest with knobs, but these features soften and fade with age, adults being smoother and flatter. For determining an adult slider's sex, males typically have much longer front claws than adult females, while females usually have shorter, more slender tails than males. Their lifespans range from 20 to 50 years.

The origin of the name slider stems from the behavior of these turtles when startled. Groups of sliders, sometimes quite large, as well as many other types of less abundant freshwater turtles, are often seen basking and sunning on logs, branches, and vegetation at or even well above the water's surface, but they readily and quickly scramble if they sense danger, shooting back in and darting away to safety underwater.

Pond sliders are native to the south-central and southeastern United States and northern Mexico.

In the 1900s, many pond sliders were captured for sale. In the 1950s, millions of turtles were being farmed and shipped abroad as part of the pet trade.

These turtles often compete with native species for food, habitat, and other resources. Eventually, they bully many native species out of basking sites, where sunlight (and warmth) is available for the species. When basking, pond sliders commonly bask on birds' nests, thereby killing the eggs. They also prey on young birds.

Turtles that were raised in captivity can develop diseases that are unfamiliar to native species, which can be harmful. Turtles raised in captivity are often released because they become too much to handle or grow bigger than expected. Not uncommonly, they also escape.
