Cold-blooded animals will move around during the day be-

tween the shade and the sun to warm up or cool down.

Cold-blooded animals are ectothermic, which means outside

heat.

Reptiles, amphibians, and fish are all cold-blooded.

Warm-blooded animals are able to regulate their internal tem-

perature. They can sweat or pant to cool off and have fur and
feathers to help keep them warm.

Warm-blooded animals are called endothermic, meaning "heat

inside".

Only birds and mammals are warm-blooded.
