Newly Identified Cascade Frog Highlights Nagaland's Biodiversity

Researchers have identified a previously unknown species of cascade-dwelling frog in Nagaland's Kiphire district, showcasing the region's rich but largely unexplored biodiversity. The finding was made by a team from the Zoological Survey of India and associated institutions during field expeditions in August 2024.

The new frog belongs to the Amolops genus, known for inhabiting Asia's fast-flowing streams. It has been named after the late zoologist Kamal Choudhury. Detailed morphological and genetic analyses have shown that it marks a unique evolutionary branch within the Amolops indoburmanensis species complex. This discovery challenges previous views that suggested a single widespread species for this group, revealing instead multiple hidden lineages across northeast India and Myanmar.

Dhriti Banerjee, Director of the Zoological Survey of India, emphasized the importance of ongoing faunal surveys and scientific documentation in appreciating and conserving India's biodiversity. Bikramjit Sinha, who led the field expedition, noted the region's rugged terrains and isolated watersheds continue to harbor amphibian diversity, reinforcing the area's status as a global biodiversity hotspot.
