Describe how an ectothermic animal may cool itself if the environmental temperatures are too high. (1 mechanism is sufficient)

Ectotherms are those animals whose body temperature increases and decreases along with the temperature of their surroundings. Examples are reptiles, amphibians. Ectotherms such as lizards, snakes regulate their body temperature not by producing metabolic heat but they follow other ways. One such way is by going into sleep, winter sleep (hibernation) and summer sleep (aestivation).
