Unknown species may thrive in Antarctic caves

8 September 2017
Animals and plants may be living in warm caves under Antarctica's ice, according to a study.
Australian researchers said that Mount Erebus, an active volcano on Antarctica's Ross Island, is surrounded by caves hollowed out in the ice by steam.
Soil samples retrieved from the caves have revealed intriguing traces of DNA from mosses, algae and small animals.
The research has been published in the journal Polar Biology.
"It can be really warm inside the caves - up to 25C in some caves. You could wear a T-shirt in there and be pretty comfortable," said co-author Dr Ceridwen Fraser, from the Australian National University (ANU) in Canberra.
"There's light near the cave mouths, and light filters deeper into some caves where the overlying ice is thin."
