Some ocean fish avoid cold temperatures by migrating to warmer waters, but fish that live near the poles have evolved an antifreeze protein that is more effective than car antifreeze, enabling them to live in temperatures below the freezing point of their blood.
Do fish eat in the winter?
Emphatically, yes! Fish are cold blooded creatures, which is crucial to consider. They differ from humans because our internal body temperature is 98.6 degrees, while theirs changes accordingly to the environment.
