WASHINGTON – In a surprising discovery about where higher life can thrive, scientists for the first time found a shrimp-like creature and a jellyfish frolicking beneath a massive Antarctic ice sheet.
Six hundred feet below the ice where no light shines, scientists had figured nothing much more than a few microbes could exist.
That's why a NASA team was surprised when they lowered a video camera to get the first long look at the underbelly of an ice sheet in Antarctica. A curious shrimp-like creature came swimming by and then parked itself on the camera's cable. Scientists also pulled up a tentacle they believe came from a foot-long jellyfish.
"We were operating on the presumption that nothing's there," said NASA ice scientist Robert Bindschadler, who will be presenting the initial findings and a video at an American Geophysical Union meeting Wednesday. "It was a shrimp you'd enjoy having on your plate."
"We were just gaga over it," he said of the 3-inch-long, orange critter starring in their two-minute video. Technically, it's not a shrimp. It's a Lyssianasid amphipod, which is distantly related to shrimp.
The video is likely to inspire experts to rethink what they know about life in harsh environments. And it has scientists musing that if shrimp-like creatures can frolic below 600 feet of Antarctic ice in subfreezing dark water, what about other hostile places? What about Europa, a frozen moon of Jupiter?
"They are looking at the equivalent of a drop of water in a swimming pool that you would expect nothing to be living in and they found not one animal but two," said biologist Stacy Kim of the Moss Landing Marine Laboratories in California, who joined the NASA team later. "We have no idea what's going on down there."
Microbiologist Cynan Ellis-Evans of the British Antarctic Survey called the finding intriguing.
"This is a first for the sub-glacial environment with that level of sophistication," Ellis-Evans said. He said there have been findings somewhat similar, showing complex life in retreating ice shelves, but nothing quite directly under the ice like this.
Ellis-Evans said it's possible the creatures swam in from far away and don't live there permanently.
But Kim, who is a co-author of the study, doubts it. The site in West Antarctica is at least 12 miles from open seas. Bindschadler drilled an 8-inch-wide hole and was looking at a tiny amount of water. That means it's unlikely that that two critters swam from great distances and were captured randomly in that small of an area, she said.
Yet scientists were puzzled at what the food source would be for these critters. While some microbes can make their own food out of chemicals in the ocean, complex life like the amphipod can't, Kim said.
So how do they survive? That's the key question, Kim said.
"It's pretty amazing when you find a huge puzzle like that on a planet where we thought we know everything," Kim said.


LIFE ALWAYS FINDS A WAY!!!!

NASA IS STUPID!

Please Quote me on that,

Please give me millions of dollars I would stretch out that budget so thin that everything that is put on there will fail the first 18 times............????

Sounds Familiar doesn't it Nasa?

I would tend to agree with you about NASA...cause if you think about it on a large scale.....if Aliens are real and piloting spacecraft than can travel the at the speed of light all the while being powered by a generator the size of a household toaster...NASA's multi-million dollar rocket launches would be worthless and they would all be out of a job!

It would be like trying to win the Indie 500 riding a moped.......no comparison!

NASA aside.....the fact that "somebody" has, again, discovered life on our own planet that they never though could have survived in that hostile environment...is pretty amazing.

It just goes to show how little we know of our own world, much less others
