Why Strategic Retreat?

The creator's reasoning behind this Animal Principle and the biology that supports it.

Sunbathing Sentinel. The Black Spiny-tailed Iguana has a unique ability to regulate its body temperature by basking in the sun. This helps it stay active and alert in its tropical habitat. When it gets too hot, it can quickly retreat to the shade or burrow into the ground to cool off. If you find yourself feeling too hot while playing outside, take a break in the shade to cool down, just like the iguana does!
