Editing Mammal (section)

====Thermoregulation====
Hair length is not a factor in thermoregulation: for example, some tropical mammals such as sloths have the same length of fur length as some arctic mammals but with less insulation; and, conversely, other tropical mammals with short hair have the same insulating value as arctic mammals. The denseness of fur can increase an animal's insulation value, and arctic mammals especially have dense fur; for example, the [[musk ox]] has guard hairs measuring {{cvt|30|cm}} as well as a dense underfur, which forms an airtight coat, allowing them to survive in temperatures of {{cvt|-40|C}}.<ref name=hair/>{{rp|162–163}} Some desert mammals, such as camels, use dense fur to prevent solar heat from reaching their skin, allowing the animal to stay cool; a camel's fur may reach {{cvt|70|C}} in the summer, but the skin stays at {{cvt|40|C}}.<ref name=hair/>{{rp|188}} [[Aquatic mammal]]s, conversely, trap air in their fur to conserve heat by keeping the skin dry.<ref name=hair/>{{rp|162–163}}
