DID YOU KNOW A NEW SPECIES FOUND IN BLIND CAVE DWEELLING FISSH IN MEGHALAYA?

DID YOU KNOW A NEW SPECIES FOUND IN BLIND CAVE DWEELLING FISSH IN MEGHALAYA? The caves of Meghalaya are home to species of blind fish, a type of loach. Schistura larketensis or the Khung loach is the second species to be discovered from the cave systems of the Jaintia hills. This species is particularly threatened by mining, pollution and hunting in the adjoining areas since its population size is very small. A new species of eyeless fish has been discovered from deep within an extensive cave system in Meghalaya. The small, slender freshwater loach has been described from Krem Khung, a limestone cave situated about 1.5 kilometres from Larket village in the Jaintia Hills District of Meghalaya. Locally known as ‘tyrlen’, the scientists have named it Schistura larketensis, the ‘Khung loach’. “When a torchlight is focused on the fish in an aquarium or its natural habitat, there is no visible reaction,” said study author Dandadhar Sarma, professor of Fish B...
