To prevent overheating, red kangaroos lick their forearms, which are crammed with a network of blood vessels and capillaries. As the saliva evaporates, it reduces their overall body temperature.

Pelicans and other birds use a technique called "gular fluttering," which sees them open their mouths and rapidly vibrate their moist throat membranes to cause evaporation.

The mucus wets the tip of their snouts, cooling large pools of blood in their beak when the moisture evaporates.

The surface of a thorny devil lizard's skin has a network of miniscule grooves that allow it to "drink" through its body. Moisture soaked up from the sand travels via capillaries to its mouth.

Marabou storks are one long-legged bird known to excrete on their legs when overheated. As the liquid -- a mixture of feces and urine -- evaporates, it cools their bodies.

Most pet-owners will have seen a "sploot", but less will know its a form of heat-dumping. Dogs, cats, and even squirrels, will adopt a flat-out, prone posture to cool themselves in high temperatures.

Wild boars are one of many species that wallow in mud to cool off. As the mud evaporates, it carries away body heat.
