Shrimp found in Antarctica at a depth of 180 m
April 9, 2010
One truly surprising news is that some researchers who participated in a joint NASA and National Science Foundation expedition stationed in Antarctica, at some point under the Ross Sea ice sheet at a depth of 180m, found some sort of shrimp swimming in the observation shaft. excavated by them to study the ice.
The small crustacean, a distant relative of the shrimp, has been identified as a Lysianassidae of the order Amphipoda about seven centimeters long. The crustacean was spotted swimming in the darkness, inside the hole of about 20 cm that had been dug in the ice and inside which a camera flew.
Scientists agree that surely those places are not the permanent home of the small crustacean but they assume that it was carried by the sea currents. However, they do not explain how it can survive 180 m deep in the darkness of the Antarctic ice because such a complex life form certainly cannot feed on the chemicals dissolved in the water as do the microbes that are usually found at those depths.
This discovery opens up interesting horizons and perspectives on the possibilities of finding life even in places so far from our imagination as to make them seem impossible, such as finding complex life forms under the ice of the planet Mars.
