Body Temperature Regulation
Reptiles
Most are ectotherms
They have low metabolic rate and keep warm by behavioral adaptations
They have dry skin which reduces the loss of body heat through evaporative cooling
Fish
Some fish are able to maintain a core temperature that is significantly greater than the water that surrounds them
smaller vessels are arranged in a countercurrent heat exchanger called the rete mirabile.
The temperature of the water that the fish lives in plays a large role in its body temperature.
Birds
Birds are homeothermic endotherms meaning that they can maintain body temperature through metabolic heat
Some have mechanisms to prevent heat loss (i.e. feathers)
Most active and behaviorally complex
Mammals
Most active and behaviorally complex
Some have mechanisms to prevent heat loss (i.e. fur)
Mammals are homeothermic endotherms meaning that they can maintain body temperature through metabolic heat
Amphibians
Have difficulty controlling heat
Behavioral adaptations enable them to maintain their body temperature
Most are ectotherms
