Capybaras have among their most amazing ability a sophisticated heat control system. These animals have evolved several ways to keep ideal body temperature in different surroundings. Their fur structure varies annually to fit temperature fluctuations; their skin features specialised blood vessels that can dilate or constrict to control heat loss. Not just for temperature control but also for sun protection and parasite defence, they employ mud wallowing behaviour during hot seasons. The mud forms a natural sunscreen and cooling mechanism's protective layer on their skin. They also use strategic scheduling of their actions; they are more active at cooler times of day to reduce heat stress.
