Zebra
Scientific name: Equus quagga
Zebras are members of the horse family native to central and southern Africa.Zebras are best known for their distinctive black and white stripes. Their stripes come in different patterns unique to each individual.
Range and habitat
Zebra habitat is from southeastern Sudan to South Africa, Kenya, Namibia, Ngorongoro Crater, Tanzania, Etosha NP, and west to Angola, in Somali-Masai Arid Zone, Southern Savanna, and South West Arid Zone.
Zebra occur in a variety of habitats, such as grasslands, savannas, woodlands, thorny scrublands, mountains, and coastal hills.
Physical characteristics
The common plains zebra is about 50–52 inches at the shoulder with a body ranging from 6–8.5 feet long with an 18-inch tail. It can weigh up to 770 pounds (350 kg), males being slightly bigger than females. Grévy's Zebra is considerably larger, while the mountain zebra is somewhat smaller.
It was previously believed that zebras were white animals with black stripes,The stripes are typically vertical on the head, neck, forequarters, and main body, with horizontal stripes at the rear and on the legs of the animal.
Like horses, zebras walk, trot, canter and gallop. They are generally slower than horses, but their great stamina helps them outpace predators. When chased, a zebra will zig-zag from side to side, making it more difficult for the predator. When cornered, the zebra will rear up and kick or bite its attacker.
Zebras have excellent eyesight and have excellent hearing.
Subspecies
There are three species and many subspecies.
The Plains Zebra (Equus quagga, formerly Equus burchelli) is the most common, and has or had about 5 subspecies distributed across much of southern and eastern Africa. It, or particular subspecies of it, have also been known as the Common Zebra, the Dauw, Burchell's Zebra (actually the extinct subspecies, Equus quagga burchelli), and the Quagga (another extinct subspecies, Equus quagga quagga).
The Mountain Zebra (Equus zebra) of southwest Africa tends to have a sleek coat with a white belly and narrower stripes than the Plains Zebra. It has two subspecies and is classified as endangered.
Grevy's Zebra (Equus grevyi) is the largest type, similar in appearance to Grevy's Zebra but with an erect mane, and a long, narrow head making it appear rather mule-like. It is a creature of the semi-arid grasslands of Ethiopia, Somalia, and northern Kenya. It is endangered too.
Feeding and diet
Zebras feed almost entirely on grasses, but may occasionally eat shrubs, herbs, twigs, leaves and bark. Their digestive systems allow them to subsist on diets of lower nutritional quality than that necessary for other herbivores.
Reproduction
Female zebras mature earlier than the males, and a mare may have her first foal by the age of three. Males are not able to breed until the age of five or six. Mares may give birth to one foal every twelve months.
Single foals weighing 30-35kg (66-77lbs) are born at any time of year after a gestation of 360-390 days. Foals can stand after about 10 minutes, start eating grass within a few days and wean at 11 months.
Predatory
The lion and spotted hyena are about the only predators that can take on an adult Zebra, with the foals being preyed upon more when given the choice. However, many mares are taken when there is not a stallion around to help protect them and their young.
Life expectancy
Its life span is between 30 to 25 years.
