Freezing Resistance in Polar Fishes
Arctic and antarctic fishes, living in contact with sea ice at -1.9°C, have plasma equilibrium freezing points near -1.2°C which are dependent on salt concentrations. These supercooled fishes have plasma protein concentrations much higher than other polar animals have, and the proteins impede ice pr...

| Summary: | Arctic and antarctic fishes, living in contact with sea ice at -1.9°C, have plasma equilibrium freezing points near -1.2°C which are dependent on salt concentrations. These supercooled fishes have plasma protein concentrations much higher than other polar animals have, and the proteins impede ice propagation at temperatures down to -2°C. Plasma protein concentration increases as environmental water temperature decreases. |
