A desert beetle in northern Mexico can change its behavior to regulate its body temperature above 35c. When would being in a burrow not be the best option for cooling off?

Temperatures, which range from freezing to well over 100F (38C), make maintaining a safe body temperature a constant challenge. Add to this the catch-22 of desert survival: an organism's need for water increases as temperature rises-available water usually decreases the hotter it gets. This might sound like an impossible situation, yet, as we'll see, desert birds and mammals have developed many adaptive strategies for coping with temperature extremes and limited water. The primary strategy for dealing with high desert temperatures is avoidance-many mammals simply avoid the high daytime temperatures.
