How amphibians regulate their body temperature?

Frog temperature. Frogs are ectotherms, this means they gettheir heat from external sources. They are sometimes called 'cold blooded', but in fact they do not have cold blood, it is justregulated by their environment. In comparison, humans are endotherms and can maintain their body temperature at about 37°C.

Amphibians are ectothermic or cold-blooded. This means that they do not maintain a constant body temperature like endotherms (like humans) do. The amphibian’s body temperature is controlled by the surrounding environment and nearly matches that temperature. Amphibians behaviorally will move or do activities to adjust their body temperature. For example, if they are too hot they will move to the shade and if they are too cold they will move to a sunny area. Some frogs secrete fluids to help maintain their moisture and temperature in extreme environments or conditions.
