Effect of environmental temperature on Antarctic fish antifreeze protein activity and concentration
… group of fishes in this region is the suborder Notothenioidei. For notothenioid fishes blood serum osmolytes only depress the freezing point of their blood to about -1.0°C, almost a full degree warmer than the environmental freezing point. The success of this group in the Southern Ocean is …

The influence of environmental temperature on the thermal tolerance of Antarctic notothenioid fishes
… a small monophyletic group within the suborder Notothenioidei, they mirror the larger group’s divisions in geographic distribution and lifestyle making this family a useful system for understanding the larger group. Within this family, blood serum freezing point was negatively correlated with …

Effects of Hyperoxia on Thermal Tolerance and Indicators of Hypoxic Stress in Antarctic Fishes That Differ in Expression of Oxygen-Binding Proteins
Antarctic icefishes (Family Channichthyidae) are unique in lacking the oxygen carrier hemoglobin (Hb) in their blood, leaving them with only 10% of the oxygen-carrying capacity observed in closely related red-blooded fishes. Previous studies have shown that icefishes have lower critical thermal …
