Hidden Wonders: New Fish Species Found in Assam Wells
22 Oct
Summary
- Two new subterranean fish species were discovered in wells.
- One species, Gitchak nakana, is tiny, blind, and transparent.
- Discovery highlights Assam's unexplored underground biodiversity.
Two previously unknown subterranean fish species have been identified in wells located in Assam's Goalpara district. The discoveries of Gitchak nakana and Rakthamichthys anchi shed light on the largely unexplored underground biodiversity of the region.
Both species inhabit groundwater environments. Gitchak nakana is a small, blind loach measuring approximately 2 cm, notable for its transparent body that reveals its internal organs. Rakthamichthys anchi is described as a slender, transparent, eel-like fish belonging to the swamp eel family.
Researchers utilized micro-computed tomography (micro-CT) scanning for detailed examination, collaborating with international scientists. The discovery emphasizes how aquatic life adapts to light-deprived conditions and raises concerns about the vulnerability of these hidden ecosystems to pollution.
Precise collection sites have been withheld to protect the species from potential exploitation. The discovery reinforces the importance of documenting biodiversity beyond visible landscapes and encourages community reporting of unusual wildlife sightings to researchers.
