Webbfishes because of their increased physiological function associated with regional heat reten-tion (8, 15). However, these fishes fall far short of whole-body endothermy because much of the body (including vital organs such as the heart) remains at ambient temperature, which ulti-mately puts limits on aerobic performance in cold water (16, 17). WebbThermoregulation allows animals to control their internal body temperature in environments that are outside their thermoneutral range.
