Cold Adaptation and Stenothermy in Antarctic Notothenioid Fishes: What Has Been Gained and What Has Been Lost?
Antarctic notothenioid fishes inhabit the coldest and most thermally stable waters in the ocean. During their evolutionary histories, these fishes have adapted to the threats posed by potentially freezing temperatures as well as the decelerating effects of reduced temperatures on rates of physiological processes. Cold adaptation of numerous biochemical systems has been a major feature of the evolutionary development of these species [1, 2, 3, 4].
