What is black and white and read all over?An embarrassed zebra!
Zebras are several species of African horse family united by their distinctive black and white stripes. Their stripes come in different patterns, unique to each individual. They are generally social animals that live in small harems to large herds. Unlike their closest relatives, horses and asses, zebras have never been truly domesticated. The zebras I saw were Plains Zebras.
The unique stripes of zebras make them one of the animals most familiar to people. They occur in a variety of habitats, such as grasslands, savannas, woodlands, thorny scrublands, mountains, and coastal hills.
The Common, Plains or Burchell’s (all the same) 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 lb., males being slightly bigger than females.
It was previously believed that zebras were white animals with black stripes, since some zebras have white underbellies. Embryological evidence, however, shows that the animal’s background color is black and the white stripes and bellies are additions. It is likely that the stripes are caused by a combination of factors.
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. The “zebra crossing” is named after the zebra’s black and white stripes.
A wide variety of hypotheses have been proposed to account for the evolution of the striking stripes of zebras. The more traditional of these (1 & 2, below) relate to camouflage.
1. The vertical striping may help the zebra hide in grass. While seeming absurd at first glance, considering that grass is neither white nor black, it is supposed to be effective against the zebra’s main predator, the , which is color blind. In addition, even at moderate distances, the striking striping merges to an apparent grey.
2. Another hypothesis is that since zebras are herd animals, the stripes may help to confuse predators—a number of zebras standing or moving close together may appear as one large animal, making it more difficult for the lion to pick out any single zebra to attack.
3.It has been suggested that the stripes serve as visual cues and identification. Although the striping pattern is unique to each individual, it is not known whether zebras can recognize one another by their stripes.
5. Alternative theories include that the stripes coincide with fat patterning beneath the skin, serving as a thermo-regulatory mechanism for the zebra, or that wounds sustained disrupt the striping pattern to clearly indicate the fitness of the animal to potential mates.
Zebras, 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
