Hyenas or hyaenas are feliform carnivoran mammals belonging to the family Hyaenidae. With just four extant species, it is the fifth-smallest family in the order Carnivora and one of the smallest in the class Mammalia. Despite their low diversity, hyenas are unique and vital components of most African ecosystems.
The Serengeti ecosystem is a geographical region in Africa, spanning the Mara and Arusha Regions of Tanzania. The protected area within the region includes approximately 30,000 km2 (12,000 sq mi) of land, including the Serengeti National Park and several game reserves. The Serengeti hosts the world's most massive land animal migration, which helps secure it as one of the Seven Natural Wonders of Africa.
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 plains zebra is the most common and geographically widespread species of zebra. Its range is fragmented, but spans much of southern and eastern Africa south of the Sahara. Six or seven subspecies have been recognised, including the extinct quagga which was thought to be a separate species. More recent research supports variations in zebra populations being clines rather than subspecies.
The honey badger, also known as the ratel, is a mammal widely distributed in Africa, Southwest Asia, and the Indian subcontinent. Because of its wide range and occurrence in a variety of habitats, it is listed as Least Concern on the IUCN Red List.
Scavengers are animals that consume dead organisms that have died from causes other than predation or have been killed by other predators. While scavenging generally refers to carnivores feeding on carrion, it is also a herbivorous feeding behavior. Scavengers play an important role in the ecosystem by consuming dead animal and plant material. Decomposers and detritivores complete this process, by consuming the remains left by scavengers.
The African buffalo is a large sub-Saharan African bovine. There are five subspecies that are recognized as valid by most authorities:
The striped hyena is a species of hyena native to North and East Africa, the Middle East, the Caucasus, Central Asia, and the Indian subcontinent. It is the only extant species in the genus Hyaena. It is listed by the IUCN as near-threatened, as the global population is estimated to be under 10,000 mature individuals which continues to experience deliberate and incidental persecution along with a decrease in its prey base such that it may come close to meeting a continuing decline of 10% over the next three generations.
The spotted hyena, also known as the laughing hyena, is a hyena species, currently classed as the sole extant member of the genus Crocuta, native to sub-Saharan Africa. It is listed as being of least concern by the IUCN due to its widespread range and large numbers estimated between 27,000 and 47,000 individuals. The species is, however, experiencing declines outside of protected areas due to habitat loss and poaching. Populations of Crocuta, usually considered a subspecies of Crocuta crocuta, known as cave hyenas, roamed across Eurasia for at least one million years until the end of the Late Pleistocene. The spotted hyena is the largest extant member of the Hyaenidae, and is further physically distinguished from other species by its vaguely bear-like build, rounded ears, less prominent mane, spotted pelt, more dual-purposed dentition, fewer nipples, and pseudo-penis. It is the only placental mammalian species where females have a pseudo-penis and lack an external vaginal opening.
Pachycrocuta is an extinct genus of prehistoric hyenas. The largest and most well-researched species is Pachycrocuta brevirostris, colloquially known as the giant short-faced hyena as it stood about 90–100 cm (35–39 in) at the shoulder and it is estimated to have averaged 110 kg (240 lb) in weight, approaching the size of a lioness, making it the largest known hyena. Pachycrocuta first appeared during the late Miocene. By 800,000 years ago, it became locally extinct in Europe, with it surviving in East Asia until at least 500,000 years ago, and possibly later elsewhere in Asia.
Tarangire National Park is a national park in Tanzania's Manyara Region. The name of the park originates from the Tarangire River that crosses the park. The Tarangire River is the primary source of fresh water for wild animals in the Tarangire Ecosystem during the annual dry season. The Tarangire Ecosystem is defined by the long-distance migration of wildebeest and zebras. During the dry season thousands of animals concentrate in Tarangire National Park from the surrounding wet-season dispersal and calving areas.
Surplus killing, also known as excessive killing, henhouse syndrome, or overkill, is a common behavior exhibited by predators, in which they kill more prey than they can immediately eat and then they either cache or abandon the remainder. The term was invented by Dutch biologist Hans Kruuk after studying spotted hyenas in Africa and red foxes in England.
Cave hyena are extinct species or subspecies of hyena known from Eurasia, which ranged from Western Europe to eastern Asia and Siberia during the Pleistocene epoch. It is well represented in many European caves, primarily dating to the Last Glacial Period. It was an apex predator that preyed on large mammals, and was responsible for the accumulation of hundreds of large Pleistocene mammal bones in areas including horizontal caves, sinkholes, mud pits, and muddy areas along rivers.
Sabi Sabi is a private game reserve in South Africa, situated in the Sabi Sand Game Reserve which flanks the south western section of the Kruger National Park. The Sabi Sand Reserve is one of the parks that make up the Greater Kruger National Park.
The wildlife of Kenya refers to its fauna. The diversity of Kenya's wildlife has garnered international fame, especially for its populations of large mammals. Mammal species include lion, cheetah hippopotamus, African buffalo, wildebeest (Connochaetes), African bush elephant, zebra (Equus), giraffe (Giraffa), and rhinoceros. Kenya has a very diverse population of birds, including flamingo and common ostrich.
The red hartebeest, also called the Cape hartebeest or Caama, is a subspecies of the hartebeest found in Southern Africa. More than 130,000 individuals live in the wild. The red hartebeest is closely related to the tsessebe and the topi.
The African wild dog, also known as the painted dog or Cape hunting dog, is a wild canine native to sub-Saharan Africa. It is the largest wild canine in Africa, and the only extant member of the genus Lycaon, which is distinguished from Canis by dentition highly specialised for a hypercarnivorous diet and by a lack of dewclaws.
Barcelona Zoo is a zoo in the Parc de la Ciutadella in Barcelona, Catalonia, Spain. The zoo used to be internationally known as the home of Snowflake, the only known albino gorilla, who died in 2003.
Tanzania contains some 20 percent of the species of Africa's large mammal population, found across its reserves, conservation areas, marine parks, and 17 national parks, spread over an area of more than 42,000 square kilometres (16,000 sq mi) and forming approximately 38 percent of the country's territory. Wildlife resources of Tanzania are described as "without parallel in Africa" and "the prime game viewing country". Serengeti National Park, the country's second largest national park area at 14,763 square kilometres (5,700 sq mi), is located in northern Tanzania and is famous for its extensive migratory herds of wildebeests and zebra while also having the reputation as one of the great natural wonders of the world. The Ngorongoro Conservation Area, established in 1959, is a UNESCO World Heritage Site and inhabited by the Maasai people. Its Ngorongoro Crater is the largest intact caldera in the world.
Pursuit predation is a form of predation in which predators actively give chase to their prey, either solitarily or as a group. It is an alternate predation strategy to ambush predation — pursuit predators rely on superior speed, endurance and/or teamwork to seize the prey, while ambush predators use concealment, luring, exploiting of surroundings and the element of surprise to capture the prey. While the two patterns of predation are not mutually exclusive, morphological differences in an organism's body plan can create an evolutionary bias favoring either type of predation.
