Gangaichthys indonepalicus described as new stygobitic fish
A 2024 TikTok video from a borewell near the India-Nepal border led to scientific scrutiny, and in 2026 the organism was formally described as a new stygobitic fish, Gangaichthys indonepalicus. A small, blind, unpigmented “earthworm eel”, it lives entirely in groundwater beneath the Gangetic Basin (family Chaudhuriidae; order Synbranchiformes). Fieldwork across 15 sites pumped thousands of litres, yielding three specimens. Naming reflects Ganga and India-Nepal; findings expand Indo-Gangetic groundwater biodiversity understanding.
