  • Scientists stumbled upon life under 3,000 feet of ice in Antarctica.

  • They found two types of unidentified animals, where they had thought nothing could live.

  • Their next step is finding a way to get close enough to identify the creatures.

Scientist have found life under 3,000 feet under of ice in Antarctica, challenging their assumption that nothing could live in such conditions.

The previous theory was that life couldn't exist in such extremity: no food, freezing temperatures, and complete darkness.

The creatures were found attached to a boulder in the frigid seas under the Filchner-Ronne ice shelf. Experts from the British Antarctic Survey drilled through 2,860 feet of ice and then another 1,549 feet of water before making the discovery.

"The area underneath these ice shelves is probably one of the least-known habitats on Earth," said Huw Griffiths, one of the scientists who made the discovery, in a Twitter video.

"We didn't think that these kinds of animals, like sponges, would be found there."

The Filchner-Ronne ice shelf is a massive floating ice sheet that stretches out from Antarctica.

It spans more than 579,000 square miles, but little has been explored under the ice.

Enormous icebergs occasionally break off ice shelves and drift away. In December, one of these icebergs threatened to crash into a breeding ground for sealions and penguins.

The scientists didn't set out looking for life.

They were drilling through the ice sheet to collect samples from the sea floor. Instead, their camera hit a boulder. When they reviewed the camera's footage, it revealed this discovery.

"Never in a million years would we have thought about looking for this kind of life, because we didn't think it would be there," Griffiths told The Guardian.

The video reveals two types of unidentified animals, shown here in a video from the British Antarctic Survey. The animals in red seem to have long stalks, whereas another type of animal, highlighted in white, looks more like a round sponge-like animal.

Other studies had looked at life under ice sheets. A few mobile animals, such as fish, worms, jellyfish, or krill, could be found in that habitat.

But it was thought that the deeper and farther away from a light source the habitat stretched, the less likely that life could be found.

The scientists say these animals are about 160 miles from the open sea.

"Our discovery raises so many more questions than it answers, such as how did they get there?" Griffith said in a press release. "What are they eating? How long have they been there?"

The scientists said their next step was to understand whether the animals were from a previously unknown species.

"To answer our questions we will have to find a way of getting up close with these animals and their environment," Griffiths said.

They are so remote that the first case of COVID-19 on the continent was only reported in December.
