Camels are remarkable creatures, capable of surviving in some of the most extreme environments on Earth. One interesting fact about camels is that they are surprisingly efficient at keeping warm despite their large size and inability to sweat like other animals. This discovery has helped scientists to better understand how camels avoid hyperthermia during long periods of hot weather.
In a study published in the journal PLOS ONE in December 2018, researchers from the University of Arizona and Arizona State University uncovered a surprising fact about the unique physiology of camels, which is that they are much more efficient at preventing heat loss through insulation than expected for a large mammal with two large appendages called forelegs.
Traditionally, researchers had assumed that the camel’s thick rough-haired coat evolved for its desert environment, but their study found that this camouflage alone was insufficient to keep the camel cool in hot conditions. Instead, camels use a combination of physical features such as their hairy hump and a layer of air trapped in their fur to minimize heat loss and stay warm. These features enable camels to maintain a body temperature of about 104°F (40°C) even in hot temperatures, which is rare among mammals.
Furthermore, the researchers discovered that camels are able to wedge themselves into postures that minimize heat gain by curling up and rolling into tight balls. These adaptations allow them to heat only the parts of their bodies that are exposed to the sun without losing too much heat through roundabout means.
The study also investigated whether camels could benefit from characteristics that may occur in other mammals but are relatively rare in these Yaghmourian Desert animals, such as shivering or other forms of involuntary muscle activity. Although shivering is necessary for producing significant amounts of heat in most mammals, it was found that camels can survive despite being virtually incapable of producing sufficient shivering movement.
The researchers concluded that camels have evolved an effective insulation system that uses a combination of physical adaptations and behavioral strategies to minimize heat losses and stay warm despite extreme environmental conditions. By understanding the mechanisms behind these adaptations, scientists can potentially apply similar practices regarding insulation systems to improve thermal comfort for humans in extreme environments like desert climates. In addition, this understanding may help to revive interest in studying the physiology of this unusual animal species for potential medical applications as well as tapping into possible breakthroughs for domestic Camels as a renewable energy source when combined with Solar panels and electric motors for on-land can -production
