The Plains zebra (Equus quagga, formerly Equus burchellii) is the most common and geographically widespread species of zebra. It is the most recognizable grazing animal on the African continent. Their closest relatives are donkeys and horses. The sparkling coat of zebras reflects more than 70% of incoming heat, which is likely to help them survive under the scorching African sun. Each of these animals has its own unique stripe pattern, which helps identify individuals. Additionally, the striped coat is used as ideal camouflage, allowing zebras to remain unspotted by predators in the grass.
The Plains zebra is dumpy bodied with relatively short legs and a skull with a convex forehead and a somewhat concave nose profile. The neck is thicker in males than in females. The ears are upright and have rounded tips. As with all wild equids, the Plains zebra has an erect mane along the neck and a tuft of hair at the end of the tail. It is boldly striped in black and white and no two individuals look exactly alike. Compared to other species, the Plains zebra has broader stripes. The stripes are vertical on the fore part of the body and tend towards the horizontal on the hindquarters. Northern zebra populations have narrower and more defined striping; southern populations have varied but lesser amounts of striping on the under parts, the legs, and the hindquarters. Southern populations also have brown "shadow" stripes between the black and white coloring. These are absent or poorly expressed in northern zebras. The natal coat of a foal is brown and white and the brown darkens with age.
Plains zebras are intermediate in size between the larger Grévy's zebra and the smaller mountain zebra and tend to have broader stripes than both. Great variation in coat patterns exists between clines and individuals. The plains zebra's habitat is generally, but not exclusively, treeless grasslands and savanna woodlands, both tropical and temperate. They generally avoid desert, dense rainforest and permanent wetlands. Zebras are preyed upon by lions and spotted hyenas, Nile crocodiles and, to a lesser extent, leopards, cheetahs and African wild dogs.
Plains zebras are a highly social species, forming harems with a single stallion, several mares and their recent offspring; bachelor groups also form. Groups may come together to form herds. The animals keep watch for predators; they bark or snort when they see a predator and the harem stallion attacks predators to defend his harem.
The plains zebra remains common in game reserves, but is threatened by human activities, such as hunting for its meat and hide, as well as competition with livestock and encroachment by farming on much of its habitat. The loss of open grasslands due to woody plant encroachment increases predation risk and therewith habitat. Plains zebra are listed as near threatened by the IUCN as of 2016. The species population is stable and not endangered, though populations in most countries have declined sharply.
