The silver dik-dik (Madoqua piacentinii) is a small antelope found in low, dense thickets along the southeastern coast of Somalia and in Acacia-Commiphora bushland in the Shebelle Valley in southeastern Ethiopia. [1] It is the smallest species of dik-dik, with a length of 45–50 cm (18–20 in), a height of 30–33 cm (12–13 in), and a weight of 2–3 kg (4.4–6.6 lb). [3] Its back and flanks are grizzled silvery, while the limbs, ears, and muzzle are ochraceus in colour. [3] Little is known about its status, but numbers are believed to be decreasing. [1]

Together with the closely related Salt's dik-dik, this species forms the subgenus Madoqua in the genus Madoqua (other dik-diks are also in the genus Madoqua, but the subgenus Rhynchotragus). [4] [5] The taxonomy of this subgenus is complex and a matter of dispute. Though most recent authorities treat the silver dik-dik as a monotypic species, [1] [6] the silver dik-dik has been suggested as a subspecies of Swayne's dik-dik [4] (itself now usually treated as a subspecies of Salt's dik-dik).

The red gazelle is an extinct species or subspecies of gazelle. It was formerly considered a member of the genus Gazella within the subgenus Eudorcas before Eudorcas was promoted to a full genus. It is thought to have lived in the better-watered mountain areas of North Africa rather than in deserts, because of the rich colouring on the coat.

<span class="mw-page-title-main">Kirk's dik-dik</span> Species of mammal

Kirk's dik-dik is a small antelope native to Eastern Africa and one of four species of dik-dik antelope. It is believed to have six subspecies and possibly a seventh existing in southwest Africa. Dik-diks are herbivores, typically of a fawn color that aids in camouflaging themselves in savannah habitats. According to MacDonald (1985), they are also capable of reaching speeds up to 42 km/hour. The lifespan of Kirk's dik-dik in the wild is typically 5 years, but may surpass 10 years. In captivity, males have been known to live up to 16.5 years, while females have lived up to 18.4 years.
