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 (183 meters) below the ice where no light shines, scientists had figured nothing much more than a few microbes could exist.

That is why a team from the National Aeronautics and Space Administration 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 scientist Robert Bindschadler, who will be presenting the initial findings and a video at an American Geophysical Union meeting Wednesday.

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 Antarctic ice in subfreezing dark water, what about other hostile places? What about Europa, a frozen moon of Jupiter?

Marine creatures thriving by a record hot volcanic vent in the Atlantic have also boosted theories that planets other than Earth are suitable for life, scientists said on Sunday.

About 150 new types of fish were among 500 new marine species, including furry crabs and a lobster off Madagascar, found in the seas in 2006, according to researchers.

"The age of discovery is not over," said Jesse Ausubel, a program manager at the US Sloan Foundation which is a sponsor of a 10-year marine census. Finds "are provocative for NASA and for people who are interested in life in places other than the Earth", he told the Christian Science Monitor.
