Figure 4. Blood from HbA and HbA null fish.

Figure 4

Blood samples from two Antarctic notothenioid fishes illustrate a striking contrast in level of hemoglobin expression. The test tube on the right contains blood from an HbA-expressing species, Notothenia coriiceps, while the tube on the left depicts the completely HbA-null phenotype of the ‘crocodile’ icefish, Chaenocephalus aceratus.
