The wildebeest (plural wildebeest, wildebeests or wildebai), also called the gnu (pronounced /ˈnuː/[1]), is an antelope Antelope is a term referring to many even-toed ungulate species found in the family Bovidae. The term does not refer to a monophyletic group, as not all members of Bovidae are considered antelope. Instead, the term refers to a ‘miscellaneous’ group within the family encompassing the species which are not cattle, sheep, buffalo, bison, or goats of the genus The term comes from Latin genus "descent, family, type, gender" , cognate with Greek: γένος - genos, "race, stock, kin" Connochaetes. It is a hooved (ungulate Ungulates are several groups of mammals, most of which use the tips of their toes, usually hoofed, to sustain their whole body weight while moving. They make up several orders of mammals, of which six to eight survive. There is some dispute as to whether Ungulata are a cladistic (evolution-based) group, or merely a phenetic group or folk taxon () mammal.
Connochaetes includes two species, both native to Africa Africa is the world's second-largest and second most-populous continent, after Asia. At about 30.2 million km² including adjacent islands, it covers 6% of the Earth's total surface area and 20.4% of the total land area. With a billion people (as of 2009, see table) in 61 territories, it accounts for about 14.8% of the World's human population: the Black Wildebeest, or white-tailed gnu (C. gnou), and the Blue Wildebeest The Blue Wildebeest is a large ungulate mammal of the Bovid family and one of two species of wildebeest. It grows to 1.7 meters shoulder height and attains a body mass of up to 380 kilograms. They range the open plains, bushveld and dry woodlands of Southern and East Africa, realizing a life span in excess of twenty years. This herbivore is a, or brindled gnu (C. taurinus). Gnus belong to the family Bovidae A bovid is any of almost 140 species of cloven-hoofed mammals belonging to the family Bovidae. The family is widespread, being native to all continents except South America, Australia and Antarctica, and diverse: members include domestic cattle, bison, water buffalo, antelopes, gazelles, sheep, goats and the muskox, which includes antelopes, cattle, goats, and other even-toed horned ungulates.
Wildebeest grow to 3 ft 9 in (1.1 m) to 4 ft 7 in (1.4 m) at the shoulder and weigh 360–630 lb (160–290 kg). They inhabit the plains and open woodlands of Africa Africa is the world's second-largest and second most-populous continent, after Asia. At about 30.2 million km² including adjacent islands, it covers 6% of the Earth's total surface area and 20.4% of the total land area. With a billion people (as of 2009, see table) in 61 territories, it accounts for about 14.8% of the World's human population, especially the Serengeti The Serengeti ecosystem is a geographical region located in north-western Tanzania and extends to south-western Kenya between latitudes 1 and 3 S and longitudes 34 and 36 E. It spans some 30,000 km2 National Park, a UNESCO World Heritage Site in Tanzania, and Masai Mara The Masai Mara is a large park reserve in south-western Kenya, which is effectively the northern continuation of the Serengeti National Park game reserve in Tanzania. Named for the Maasai people (the traditional inhabitants of the area) and the Mara River, which divides it, it is famous for its exceptional population of game and the annual Game Reserve in Kenya. Wildebeest can live more than 20 years.
Wildebeest are well known for their annual migration to new pastures Pasture is land with low-growing vegetation cover used for grazing of livestock as part of a farm, or in ranching or other unenclosed pastoral systems. Prior to the advent of factory farming, pasture was the primary source of food for grazing animals such as cattle and horses. It is still used extensively, particularly in arid regions where. Many wildlife documentaries Documentary film is a broad category of visual expression that is based on the attempt, in one fashion or another, to "document" reality. Although "documentary film" originally referred to movies shot on film stock, it has subsequently expanded to include video and digital productions that can be either direct-to-video or made have featured this event, in which vast numbers of wildebeest can be seen crossing rivers, such as the Mara River and dying in large numbers as they attempt to reach the other side, because many of them are eaten by crocodiles A crocodile is any species belonging to the family Crocodylidae . The term can also be used more loosely to include all members of the order Crocodilia: i.e. the true crocodiles, the alligators and caimans (family Alligatoridae) and the gharials (family Gavialidae), or even the Crocodylomorpha which includes prehistoric crocodile relatives and while others simply drown. Although it is commonly assumed that this is simply a frenzy and that the wildebeest cross blindly, recent research has shown that a herd of gnu possesses what is known as a "swarm intelligence Swarm intelligence is a type of artificial intelligence based on the collective behavior of decentralized, self-organized systems. The expression was introduced by Gerardo Beni and Jing Wang in 1989, in the context of cellular robotic systems", whereby the animals systematically explore and overcome the obstacle as one.[citation needed] Wildebeest have a maximum running speed of around 64 km/h (40 mph).[citation needed]
The major predators who prey on Wildebeest are lions, hyenas, cheetahs, and leopards. However, Wildbeest are very strong and can inflict considerable injury to even a lion. The primary defense is herding where the young animals are protected by the older larger ones while the herd runs as a group. A predator in the middle would get trampled. Typically the predators attempt to cut out a young or ill animal and attack without having to worry about the herd. Wildebeest have developed some additional sophisticated cooperative behavior and scientists are unsure how much is learned behaviorally and how much is hard wired into the DNA of the animal. For example, at night the animals will take turns sleeping while others stand guard against a night attack by predators.
