Evaluating pet trade and invasion risk of the red eared slider Trachemys scripta elegans in Kerala India

The Red-eared slider (Trachemys scripta elegans) is one of the world’s most invasive reptiles, with its spread largely driven by the global pet trade. This study examines its trade dynamics in Kerala, India, a biodiversity hotspot facing increasing invasive species threats. Using a telephonic questionnaire survey of 60 individuals engaged in the pet trade, we assessed awareness, motivations, and release practices associated with Red-eared sliders. Most turtle sales started in Kerala between 2010 and 2020, primarily via Chennai. Drivers of pet ownership included children’s fascination with exotic pets, ease of maintenance, and religious beliefs. However, awareness of ecological impacts was low, as only 32% of sellers acknowledged the risks of release, and nearly half believed there was no threat. These findings underscore the urgent need for targeted outreach, strengthened regulation, and active surveillance to mitigate the invasion risk posed by this species.
