Speleological Association of India Names Neolissochilus pnar as First National Cave Animal of the Year

Correspondent

SHILLONG: In a groundbreaking initiative to spotlight India’s hidden biodiversity, the Speleological Association of India (SAI) has designated Neolissochilus pnar, the world’s largest cavefish, as the country’s inaugural “National Cave Animal of the Year.” This recognition marks a significant step in raising awareness about subterranean ecosystems and their unique ecological significance.

“This remarkable species symbolizes the hidden ecological treasures within our caves,” the SAI stated. “Through this initiative, we seek to underscore the ecological importance of cave-dwelling species and ensure their long-term protection.”

Discovered during 2019 and 2020 expeditions in Meghalaya’s East Jaintia Hills, the cavefish was found in the Krem Um Ladaw and Krem Chympe caves. Named after the Pnar, a sub-tribal group of the Khasi people, the species honors their deep cultural and environmental connection to the region.

Adapted to life in darkness, Neolissochilus pnar exhibits traits such as reduced or absent eyes and a lack of pigmentation. The species inhabits the rocky, water-filled chambers of Krem Um Ladaw and the deep tunnels and waterfalls of Krem Chympe.

A collaborative team of researchers, including Neelesh Dahanukar (Shiv Nadar Institution of Eminence), Remya L. Sundar (Kerala University of Fisheries and Ocean Studies), Duwaki Rangad (St. Edmund’s College, Shillong), Graham Proudlove (The Manchester Museum), and Rajeev Raghavan (Kerala University of Fisheries and Ocean Studies), formally described the species.

The “Cave Animal of the Year” campaign, launched by SAI, seeks to promote scientific exploration, public engagement, and conservation efforts for India’s often-overlooked subterranean ecosystems, ensuring their protection for future generations.
