Aspects of Eco-Physiological Adaptations in Antarctic Fish

ambient water temperature and depth due to the metabolic cost of
synthesizing these glycopeptides and peptides. High lipid contents, highly
glycosylated gangliosides and freezing resistance in fish are important
adaptations to life in high-Antarctic waters. However, low water
temperature as such has not caused the paucity of nonnotothenioid species
in the Antarctic fish fauna.
