Penguins in Antarctica to be replaced by jellyfish due to global warming http://apocadocs.com/s.pl?1266593570
The results of the largest ever survey of Antarctic marine life reveal melting sea ice is decimating krill populations, which form an integral part of penguins' diets.
The six-inch-long invertebrates, also eaten by other higher Southern Ocean predators such as whales and seals, are being replaced by smaller crustaceans known as copepods. These miniscule copepods, measuring just half a millimetre long, are too small for penguins but ideal for jellyfish and other similarly tentacled predators.... Any decrease in sea ice will inevitably affect the delicate balance of the Antarctic marine food chain.
For creatures such as penguins who lives on the melting sea ice, a rise in temperatures will also shrink the size of their breeding grounds.
