El Ojo ‘The Eye’ Island Location: Buenos Aires, Argentina
First discovered by Argentinian filmmaker Sergio Neuspiller in 2003, El Ojo is an uninhabited circular rotating floating island located within a slightly larger circular lake in the Paraná Delta in the Buenos Aires Province, Argentina. This island is constantly rotating on its own axis due to the flow of the river beneath it. The island was named because of its resemblance to an eye when viewed from above: as the island rotates within its surrounding circular lake, the eye appears to move.
Cryptotora thamicola or the waterfall climbing cave fish are extremely rare, found in only eight caves on the border of Thailand and Myanmar. Like most cave fish they are blind and pigmentless but what makes them special is there ability to cling to walls and climb up flowing water.
