Beatragus is a genus of alcelaphine antelope. The hirola (Beatragus hunteri) is the only living representative, but a couple of extinct species are known, all from Africa. [2]
The hirola and the larger Beatragus antiquus may together represent different phases of a chronospecies; the living hirola probably declined in size as a result of an ecologically impoverished landscape. [3]
Felidae is the family of mammals in the order Carnivora colloquially referred to as cats. A member of this family is also called a felid. The term "cat" refers both to felids in general and specifically to the domestic cat.
Jackals are medium-sized canids native to Africa and Eurasia. While the word "jackal" has historically been used for many canines of the subtribe canina, in modern use it most commonly refers to three species: the closely related black-backed jackal and side-striped jackal of sub-Saharan Africa, and the golden jackal of south-central Europe and Asia. The African golden wolf was also formerly considered as a jackal.
A mammal is a vertebrate animal of the class Mammalia. Mammals are characterized by the presence of milk-producing mammary glands for feeding their young, a neocortex region of the brain, fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,400 extant species of mammals have been described and divided into 29 orders.
Squirrels are members of the family Sciuridae, a family that includes small or medium-size rodents. The squirrel family includes tree squirrels, ground squirrels, and flying squirrels. Squirrels are indigenous to the Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known fossilized squirrels date from the Eocene epoch, and among other living rodent families, the squirrels are most closely related to the mountain beaver and to the dormice.
Wildebeest, also called gnu, are antelopes of the genus Connochaetes and native to Eastern and Southern Africa. They belong to the family Bovidae, which includes true antelopes, cattle, goats, sheep, and other even-toed horned ungulates. There are two species of wildebeest: the black wildebeest or white-tailed gnu, and the blue wildebeest or brindled gnu.
The hippopotamus, also shortened to hippo, further qualified as the common hippopotamus, Nile hippopotamus, or river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus. Its name comes from the ancient Greek for "river horse" (ἱπποπόταμος).
The subfamily Alcelaphinae, of the family Bovidae, contains the wildebeest, tsessebe, topi, hartebeest, blesbok and bontebok, and several other related species. Depending on the classification, there are 6–10 species placed in four genera, although Beatragus is sometimes considered a subgenus of Damaliscus, while Sigmoceros is sometimes considered for the Lichtenstein's hartebeest.
The hirola, also called the Hunter's hartebeest or Hunter's antelope, is a critically endangered antelope species found on the border between Kenya and Somalia. It was first described by the big game hunter and zoologist H.C.V. Hunter in 1888. It is the only living member of the genus Beatragus, though other species are known from the fossil record. The global hirola population is estimated at 300–500 animals and there are none in captivity. According to a document produced by the International Union for Conservation of Nature "the loss of the hirola would be the first extinction of a mammalian genus on mainland Africa in modern human history".
The Pedetidae are a family of mammals from the rodent order. The two living species, the springhares, are distributed throughout much of southern Africa and also around Kenya, Tanzania, and Uganda. Fossils have been found as far north as Turkey. Together with the anomalures and zenkerella, Pedetidae forms the suborder Anomaluromorpha. The fossil genus Parapedetes is also related.
The striped polecat, also called the African polecat, zoril, zorille, zorilla, Cape polecat, and African skunk, is a member of the family Mustelidae that resembles a skunk. The name "zorilla" comes from the Spanish word "zorillo", meaning "skunk", itself a diminutive form of the Spanish "zorro," "fox." It lives predominantly in dry and arid climates, such as the savannahs and open country of Central, Southern, and sub-Saharan Africa, excluding the Congo basin and the more coastal areas of West Africa.
The blesmols, also known as mole-rats, or African mole-rats, are burrowing rodents of the family Bathyergidae. They represent a distinct evolution of a subterranean life among rodents much like the pocket gophers of North America, the tuco-tucos in South America, or the Spalacidae from Eurasia.
The Arawale National Reserve is a designated conservation area managed by the Garissa County in assistance with the Kenya Wildlife Service. It lies in North Eastern Province of Kenya, 77 km south of the town of Garissa. The reserve covers an area of 53,324 hectares. To the west, it is bordered by the Tana River and, to the east, by the Garissa-Lamu road. In 1974, the reserve was gazetted as the only in-situ conservation site for the critically endangered Hirola population endemic to north-eastern Kenya and south-west Somalia.
Hippotragus is a genus of antelopes which includes two living and one recently extinct species, as well as some fossil relatives. The name comes from Greek ἵππος (híppos), "horse", and τράγος (trágos), "he-goat".
The African linsangs also known as oyans are two species classified in the mammalian subfamily Viverrinae, in the family Viverridae. There is one genus, Poiana.
Paracolobus is an extinct genus of primate closely related to the living colobus monkeys. It lived in eastern Africa in the Pliocene and Early Pleistocene. Fossils have been found in Kenya and Ethiopia, in places such as the Omo valley.
Hyraxes, also called dassies, are small, thickset, herbivorous mammals in the order Hyracoidea. Hyraxes are well-furred, rotund animals with short tails. Typically, they measure between 30 and 70 cm long and weigh between 2 and 5 kg. They are superficially similar to pikas and marmots, but are more closely related to elephants and sea cows.
The preorbital gland is a paired exocrine gland found in many species of artiodactyls, which is homologous to the lacrimal gland found in humans. These glands are trenchlike slits of dark blue to black, nearly bare skin extending from the medial canthus of each eye. They are lined by a combination of sebaceous and sudoriferous glands, and they produce secretions which contain pheromones and other semiochemical compounds. Ungulates frequently deposit these secretions on twigs and grass as a means of communication with other animals.
Beatragus antiquus, the ancient hirola, is an extinct species of alcelaphine antelope that lived in Africa during the Plio-Pleistocene.
