One lone Brazilian blind characid fish, part of the family of tetras and piranhas, was first discovered in 1962 in Minas Gerais, Brazil. It was identified by ichthyologists as a new species of Characiformes (a type of ray-finned fish), but then it was never seen again. Well, until now.
The Federal University of Sao Paulo and its team of researchers led by Dr. Cristiano Moreira have recently rediscovered the Brazilian blind characid fish in deep underground wells. Sadly, the already-small school of fish, confirmed to be the Stygichthys typhlops, is near-extinction.
