Limpets reveal possible fate of cold-blooded Antarctic animals

A limpet no bigger than a coin could reveal the possible fate of cold-blooded Antarctic marine animals as per new research published this week in The Journal of Experimental Biology. In comparison to their temperate and tropical cousins, cold-blooded polar marine animals are incapable of fast growth. Until now researchers assumed that a lack of food in winter was the major limiting factor. Studies of the protein-making abilities of limpets in both the sea around the British Antarctic Surveys (BAS) Rothera Research Station and in the laboratory aquarium reveal that these animals cannot make proteins the building blocks of growth - efficiently........
