Keeping cool in the heat
Gemsboks also raise their body temperature on hot days - up to 45 centigrade (113 Fahrenheit). A network of small blood vessels in their noses cools the air they breathe, and that keeps their brains cool too. The gemsbok's underpart is white, reflecting the heat radiating from the ground. They get fluids from water-rich foods such as roots, tubers and the tsamma melon, which grows in the desert.
