Temperature regulation is a type … Webb23 mars 2024 · Physiological Thermoregulation In Fish Physiological thermoregulation is where the fish controls its core body temperature by means of internal physiological and metabolic activities. This is also how we maintain our body temperatures. But while it is universal among mammals, it is rare in fish.

WebbThermoregulation allows animals to control their internal body temperature in environments that are outside their thermoneutral range.
