Danish scientists claim to have discovered a new class of animal living on algae in the Greenland ice.
The microscopic organism is believed to be the newest member of a recently recognised group of animals with complex jaws.
The researchers from the University of Copenhagen and the University of Aarhus say that the animal has its own branch in the tree of life.
Called Limnognathia maerski, it was found among samples collected in 1996 from cold springs on Disko Island in northern Greenland.
