MOLECULAR PHYLOGENYOF HEMOGLOBIN*□S
The Arctic and Antarctic marine faunas differ by age and isolation. Fishes of the two polar regions have undergone dif-ferent regional histories that have driven the physiological diversities. Antarctic fish are highly stenothermal, in keeping with stable water temperatures, whereas Arctic fish, bei...
