World’s largest subterranean fish discovered in Indian cave – and it’s blind

FOX News –

Scientists have discovered the world’s largest known subterranean fish in a cave in northeastern India.

The “troglomorphic fish” was discovered last year, according to recently released research. “The largest individual seen in the cave was in excess of 400 mm [15.8 inches] in standard length making it, by far, the largest known subterranean fish found to date,” scientists explain in an abstract of the study.

The discovery of the blind fish challenges previously held theories on fish dwelling in subterranean locations. “It has always been assumed that cave fishes exceeding 350 mm would be most unlikely on resource grounds but this has now been shown to be spectacularly wrong,” the researchers explain. “The fish discovered in Meghalaya in February 2019 is not only substantially longer than the longest previously known species but is considerably more bulky with a body mass likely to exceed that of the next largest cave fish by at least an order of magnitude.”

The fish is similar anatomically to the Tor Putitora, an endangered Asian fish, which is also known as the Putitor Mahseer or Golden Mahseer fish. However, the cave fish discovered in Meghalaya differs from the Tor Putitora in its “depigmentation, lack of eyes and in its subterranean habitat,” according to the new research.
