Radiolaria have traveled thousands of miles on currents into the cold water above Norway, in what scientists say is not directly linked to global warming.
Researchers from the US, Norway and Russia, collaborated in the study which found the protozoa in unfamiliar waters.
How did it get there?
Live Science reported that naturally cyclic, yet unusual ocean pulses pushed it there - pulses that some scientists believe are growing in number due to climate change.

Despite being out of their comfort zone, the organisms, which live for only about a month, are thriving.
Researchers found that the radiolaria discovered were reproducing rapidly, indicating that they can survive in colder conditions, said the Daily Mail.
The study was published in the journal British Journal of Micropalaeontology.
