At a time when rapid urbanisation and biodiversity loss are threatening wildlife, the Thackeray Wildlife Foundation (TWF), founded by Tejas Thackeray in 2019, has documented 116 species new to science across India, Nepal, the Democratic Republic of the Congo and Angola.

Of these, 104 were discovered in India, with findings spanning the Western Ghats, Indo-Burma and several states, including Maharashtra, Karnataka, Telangana and Rajasthan. Despite having a team of just 13 members, the Mumbai-based organisation has emerged as a leading wildlife research and conservation group. Thackeray said the foundation's work extends beyond discovering new species.

"At TWF, we take a holistic approach to conservation, emphasising the protection of biodiversity as a whole. Through field and museum-based research, on-ground conservation action and community engagement, we strive to document, protect and restore ecosystems," he said.

TWF's achievement stands out for its scale. Despite having only 13 members, the organisation has carried out scientific expeditions from the Western Ghats to Northeast India and overseas, demonstrating that major discoveries are still possible in the 21st century. "

"At the foundation, I've documented and studied remarkable arachnid diversity through extensive fieldwork in some of the most unexplored and under-surveyed landscapes. These expeditions continue to reveal how much remains to be discovered about our lesser-known fauna. What sets the foundation apart is its commitment to studying and conserving species that are often overlooked but are vital to healthy ecosystems. Through rigorous scientific research, field surveys and public outreach, we aim to bridge knowledge gaps and ensure these animals receive the recognition and attention they deserve."
