Limpets reveal possible fate of cold-blooded Antarctic animals
...urnal of Experimental Biology. Compared to their temperate and tropical cousins, cold-blooded polar marine animals are incapable of fast growth. Until now scientists assumed that a lack of food in winter was the major limiting factor.
