Category: Environment / Biodiversity Conservation

UPSC Notes

The red-eared slider (Trachemys scripta elegans) is a freshwater turtle native to the south-central United States and parts of northern Mexico. It is widely traded as a pet and has become invasive in several regions outside its native range.

Major characteristics

  • Recognisable by the red or orange patch behind each eye.

  • Lives in freshwater habitats such as ponds, lakes and slow-moving waterways.

  • Feeds on aquatic plants, invertebrates and other food sources.

  • Often introduced into natural environments through the release or escape of pet turtles.

Ecological threats

  • Competition with native turtles for food and basking sites.

  • Potential transmission of pathogens and parasites.

  • Predation on aquatic organisms.

  • Disruption of freshwater ecosystems.
