Scientists from the University of Delhi and Harvard University have discovered five new species of tiny horned frogs in India's eastern Himalayas, more than doubling the number of known species in the Jingophrys group. The study, published in the Royal Society Open Science journal, includes the first frog known in India to feed on snails.
The snail-eating horned frog, named Jingophrys tanogogo, is also the first member of its family recorded with such a diet. The discoveries followed five years of fieldwork.
The Himalayas are among the world's richest biodiversity regions, but Arunachal Pradesh in particular has emerged as one of its least studied regions. Dr Sonali Garg, who led the study at Harvard University's Museum of Comparative Zoology, said the research highlights how significant evolutionary changes can go unnoticed in little-studied species.
The new species have been named Jingophrys taniitatii (Tanii horned frog), Jingophrys tanogogo, Jingophrys siangensis (Siang horned frog), Jingophrys hrdy (Hrdy's horned frog) and Jingophrys wularsoni (Wu-Larson's horned frog). The researchers said local tribes provided essential field support, and some species were named after these communities. The Tanii horned frog's name combines the Tanii tribe with the word tatti, meaning frog in the local Apatani language.
SD Biju of Delhi University said some of the new species are extremely secretive and found in remote forests only during a short breeding season. DNA analysis showed the horned frogs rapidly diversified into multiple species as the mountain range rose and the Asian monsoon took shape over millions of years. The researchers said further studies will be needed to better understand their biology and conservation needs.
Analysis
Why This Matters
- The discovery highlights the eastern Himalayas as an overlooked hotspot for frog biodiversity and evolution, suggesting many more species may remain undiscovered.
- The snail-eating horned frog represents a unique dietary specialisation not previously recorded in this family in India.
- The findings have implications for conservation, stressing the need to study and protect poorly explored regions.
Background
The Himalayas are a globally significant biodiversity region, but the eastern section, particularly Arunachal Pradesh, has seen limited scientific exploration. The Jingophrys group of horned frogs is diverse but secretive. The study, published on 11 November in the Royal Society Open Science journal, was the result of a five year collaboration between the University of Delhi and Harvard University.
What to Watch
- Further studies to understand the biology and conservation needs of the five new species.
- Whether the findings prompt renewed conservation efforts or targeted surveys in the eastern Himalayas.
