Fish thermoregulation

WebMay 22, 2015 · If fishes didn’t have mechanisms to avoid freezing, their body fluids would freeze from -0.1 to -1.9ºC. We have to keep in mind that internal freezing of cells produce their death, what can produce the death of the animal. In any case, in a freezing process, the first that freezes are body fluids outside the cells, what suppose a less risk.
