he icefish photo below is a family of perciform fish found in the cold waters around Antartica and southern South America. It’s also called white-blooded fish due to its transparent appearence.
Interestingly, the blood is transparent because they have no hemoglobin and only defunct erythrocytes. The cold water carries enough oxygen that support the fish to live and as water can dissolve more oxygen when it’s colder. Their gills have grown large and the skin is filled with capillaries that absorb oxygen directly from the water as does a frog’s.
