Silent Invaders : Biodiversity at Risk, Social Media findings into Exotic Pet Trade in Tamil Nadu and Invasion Modeling of Iguana iguana (Linnaeus, 1758)

Abstract

This study investigates the exotic pet trade in Tamil Nadu by analyzing YouTube videos, which revealed the presence of 148 pet species being sold in pet shops. Among these, 12 species were classified as Endangered, 15 as Vulnerable, 3 as Near Threatened, 101 as Least Concern, and 18 as Not Assessed, according to the IUCN Red List. The CITES status of each species was also examined to assess their trade regulations. Additionally, the presence of invasive alien species recorded in the videos and already existing in the wild in India was mapped. Species distribution modelling using MaxEnt was conducted for Iguana iguana globally, evaluating both current and future habitat suitability. Results indicated a high potential for the species to establish itself and reproduce in India, posing a serious ecological threat. A questionnaire survey among pet shop owners disclosed limited awareness of pet trade regulations and breeding practices. Overall, the findings highlight the urgent need for stricter enforcement of pet trade laws, increased public awareness, and proactive measures to prevent potential invasions by exotic species.
