There are Shrimp Live in Antarctic Ice Depth of 180 Meters

These findings challenge the common assumption about survival of complex organisms, ie organisms that are more than just a form of bacteria or single cell only.
If any shrimp could play under a layer of ice 180 meters, how the moons of Jupiter, Europa, an ice-covered?

The scientists found the fauna of the family of crustaceans and jellyfish also survive under a thick layer of ice in Antarctica, which was presumed there would be no animal that can survive in a place like that.

Under the thick layer of ice 600 feet, or approximately 180 meters, and without sunlight, scientists had assumed that only microbes that can survive.

What a surprise team of NASA when they lower the camera to explore the waters under the Antarctic ice sheet. An animal such as shrimp swim over and landed on the camera cable. The scientists also discovered traces of tentacles are thought to have come from a type of jellyfish.

"At first we assumed there was no (animal) anything down there," said NASA scientist Robert Bindschadler, who presented the findings following the videotape, on Wednesday (17/03/2010) at the American Geophysical Union meeting.

The animal is 3 inches in length and was highlighted during the two minutes. "Just like we used to eat shrimp," Bindschadler joke. Precisely this animal is Lyssianasid Amphipod, not shrimp, but nothing to do with family crustaceans.

Why is this important discovery of a shrimp? Because of this challenge our thinking about the minimum requirement for the organism to survive. If any shrimp could play under a layer of ice 180 meters, how the moons of Jupiter, Europa, an ice-covered?

Microbiologists Cynan Ellis-Evans of the UK Antarctic survey agencies also dumbfounded by this discovery. "This discovery (animal), first on the environment under a layer of ice which is a complex organism."

He also explained that previously had found similar things in the area of ​​the ice sheet began to melt, but there has never been the discovery that just below the ice. But he also stated that the animal might have swum so far and get lost in there, so the area is not their permanent habitat.

But Kim, one of the scientists involved in the discovery were dubious allegations of 'lost animal' it. The location of the discovery that more than 19 km away from the open ocean.

Bindschadler and his team just drill a hole diameter of approximately 20 cm and only observe a very small waters. That is, it is probable that there are two organisms that swim that far and then trapped in the narrow waters.

Indeed, scientists are still puzzled what the animal food sources. According to Kim, if microbes could produce its own food from chemicals in the ocean, but complex animals like Amphipod it can not.

So, how do animals survive?
