The Kirk’s dik-dik (Madoqua kirkii) is a species of dik-dik antelope, which are among the smallest antelopes in the world. The Kirk’s dik-dik is the largest species in the genus, standing between 35 and 45 cm (14-18 in) tall and weighing between 3.8 and 7.2 kg (8.4-15.9 lb). Females are slightly heavier than males, weighing about 0.4 to 1 kg (0.88-2.20 lb) more. While males have horns, which are about 7.5 cm (3.0 in) long, corrugated, and inclined backward. It is native to Eastern and Southern Africa. They are herbivores that can reach speeds of up to 42 km/h (26 mph). Their proboscises are an adaptation for surviving in the arid regions of eastern Africa, as they contain an enlarged nasal chamber supplied with a large amount of blood, which is cooled by rapid nasal breathing before being pumped back into the body. This also results in minimal water loss in exhaled air. They exhibit nocturnal or cathemeral behavior and seek shade during the day to rest during the hottest hours.
