Scientists have confirmed the discovery of thirteen new amphibian species across Northeast India, according to researchers from the Wildlife Institute of India. The findings were announced in Shillong on Thursday 28 November.
Officials said that six of the newly described species were located in Arunachal Pradesh, three in Meghalaya and one each in Assam, Mizoram, Nagaland and Manipur. The discoveries highlight the region’s exceptional biological diversity, much of which remains under studied due to its complex terrain and limited scientific access. The research was conducted between 2019 and 2024 with support from the National Geographic Society and the Meghalaya Biodiversity Board. Field teams undertook extensive surveys in forests, river valleys and remote high altitude zones, documenting amphibians that had previously been unknown to science.
Scientists involved in the project described the discoveries as a significant contribution to understanding India’s lesser known fauna. One researcher said the findings demonstrate “how vital long term exploration is for uncovering hidden diversity”. The team also noted that amphibians are sensitive indicators of environmental change, and new species can help reveal the health of the region’s ecosystems.
The study’s authors believe the discoveries will strengthen arguments for enhanced conservation measures in the Northeast, where habitat loss and changing climatic conditions continue to challenge wildlife. Further work is planned to assess the population status of the newly identified species and to map their ecological requirements.
The results mark one of the most extensive amphibian surveys carried out in the region in recent years.
