The Damara Dik-Dik (Madoqua kirkii) is one of the smallest antelopes in Africa. It reaches a shoulder height of up to 40 centimeters and a weight of 5 kilograms. Damara Dik-Diks are diurnal animals, but on days with very high temperatures they rest in the shade during the day and are active at night. To protect against heat they cool blood in their nasal passages.
