Antarctic Lake Vostok 'might have fish'
Lake Vostok, which is located in Antarctica, about 2 ½ miles below the surface has had no contact with the atmosphere for millions of years now. Scientist have discovered DNA evidence found from drilling in the ice that there is a possibility that fish may live in the lake. With this discovery being found scientist have come to the conclusion that Antarctica has very complex set of rivers and the organisms found could most likely have been sent to Vostok from the ocean. Lake Vostok is over 200m below sea level and finding DNA and different types of organisms, even fish it was very surprising. Over time I think that this was very possible to find living organisms and even fish in the lakes, because it is a possibility that living things can survive depending on their nature. I think that scientist need to keep this study up and drill more holes in the ice to find more living things. We could come upon a new discovery of living things before our very lives. Overall Lake Vostok has new creatures living under the ice and it is our job to be able to figure out what they are and what their capable of.

The fact that fish can be living 2.5 miles underground is too cool. It comes as a surprise though; I wonder what they eat and where they get the oxygen needed to survive. Typically, fish use the oxygen produced by plants going through photosynthesis. Plants this deep underground can’t go through photosynthesis due to the lack of sunshine leaving the fish with no oxygen. I’m with you Hannah; I feel as if scientists should look more into this and drill more holes. Maybe the fish and organisms are capable of solving some of our problems here above ground.
ReplyDeleteI think the discovery of possible life in Lake Vostok is quite incredible. I agree with Madison that the situation is quite unique. I would think that fish being able to survive 2.5 miles underground would be impossible but who knows, science is always proving us wrong.
