Editing Squirrel monkey (section)

=== Thermoregulation ===
Squirrel monkeys can only sweat through the palms of their hands and the soles of their feet. Sweating in these areas alone does not provide enough cooling for the monkeys to survive in the high temperature environments of South and Central America, requiring them to use other methods to thermoregulate. They will use behavioral tactics such as seeking out shaded areas sheltered from the sun and also make use of postural changes to better dissipate heat from their body. They will also make use of a technique to maximize evaporative cooling known as urine washing. The monkeys will urinate on their hands and rub the urine over the soles of their feet. The urine is then evaporated off the body in a cooling process. Studies have shown this behavior to be maximized during times of high temperature, highlighting its importance as a thermoregulatory behavior.<ref name=":4">{{Cite journal|last=Ruiz|first=J.C|date=2005|title=Relative humidity, ambient temperature, and urine washing behavior in Bolivian squirrel monkeys, Saimiri boliviensis boliviensis.|journal=Primate Report|volume=71|pages=57–61|via=webofscience.com:WOS:ZOOREC}}</ref>
