The findings came from the Antarctica New Zealand institution which supported a number of researchers from universities in Wellington, Auckland and Otago, the National Institute of Water and Atmospherics (Niwa) and Geological and Nuclear Sciences.

“For a while, we thought something was wrong with the camera, but when the focus improved, we noticed a swarm of arthropods around 5mm in size,” said NIWA’s Craig Stevens according to The Guardian.

The organisms found in the frozen river under the ice were determined to be shrimp-like amphipods - little creatures from the same lineage as lobsters, crabs and mites.

The researchers said that they have been aware of a network of freshwater lakes underneath the ice in Antarctica but this is a major breakthrough in understanding the ecosystem of those water bodies.

The team of researchers have left instruments deep inside the water bodies and they will further studying the ecosystem and various marine organisms present.
