Белокровные рыбы ( Channichthyidae )

See clear blood run through the veins of the icefish, a demonstration of the process of natural selection. This video uses the Antarctic icefish as an excellent case study for genetic evolution and is perfect for all science classes. See how these amazing fish avoid freezing in the icy ocean. Genetic changes enable icefish to thrive without hemoglobin and red blood cells. Natural selection has resulted in the “birth” of new genes and the “death” of old ones.
