Thermoregulation is the maintenance of a stable body temperature by managing the flow of heat into and out of the body. Although there are two major strategies, exothermy (relying on external heat sources) and endothermy (relying on internally generated heat), all animals use a combination of behavioral and physiological strategies ...
WebLarge fish like tuna and sharks generate and conserve enough heat to raise their body temperature above that of the surrounding water, but unlike a true endotherm, they don't maintain a specific body temperature. Even some insects can use metabolic heat to increase body temperature by contracting their flight muscles! WebThermoregulation. Nearly all fish species are ectothermic, or cold-blooded. They are not capable of regulating their own body temperature and depend on their surrounding …
