They are sturdy, spirited animals that are a study in contrasts: willful and playful, social and standoffish, resilient and vulnerable. Their life in a herd can be complex, yet they also find safety in numbers. Zebras are equids, members of the horse family. They have excellent hearing and eyesight and can run at speeds of up to 35 miles per hour 56 kilometers per hour. They also have a powerful kick that can cause serious injury to a predator, like a lion, a hyena, or an African wild dog.

They also have a powerful kick that can cause serious injury to a predator, like a lion, a hyena, or an African wild dog.

Usually the lead male of the herd, called a stallion, sounds the alarm if danger is spotted and stays at the back of the group to defend against predators if necessary, while the mares females and foals youngsters run away. Zebras often trot when moving to new pastures, which is a fairly fast but easy gait for them to use over the long distances they may have to travel. Their hard hooves are designed to withstand the impact of their body weight and to run easily over rocky ground.

When resting at night, zebras lie down while one stands watch to prevent an ambush. Stripes: White with black or black with white? This is one of the most-asked questions about zebras. So what's up with the stripes? Zebras are generally thought to have white coats with black sometimes brown stripes. That's because if you look at most zebras, the stripes end on their belly and toward the inside of the legs, and the rest is all white.

However there had to be a catch, right? And as it turns out, zebras have black skin underneath their hair. So it depends on how you look at it! So, why the stripes? They serve as a kind of protection from predators! When zebras are grouped together, their combined stripes make it hard for a lion or leopard to pick out one zebra to chase. Different zebra species have different types of stripes, from narrow to wide.

In fact, the farther south on the African plains you travel, the farther apart the stripes on the zebras get! No zebra, or other wild equid, has a forelock.

A mountain zebra has vertical stripes on the neck and torso, which graduate to wider—and fewer—horizontal bars on the haunches. It has a gridiron pattern on the rump, and its white underside has a dark stripe that runs the length of the belly. The plains zebra is the most abundant and the smallest of the three zebra species. Mountain zebras, as their name implies, inhabit rocky, arid slopes in Namibia and Angola. Plains zebras, which are the most abundant of the three zebra species, are found from the grasslands of East Africa to the scrubby woodlands of southern Africa.

Their back teeth then crush and grind the food. Spending so much time chewing wears the teeth down, so those teeth keep growing all their lives. As the dry season arrives and the grasses die back, zebra herds travel to find more food and water holes for drinking. Most zebras are considered nomadic, without specific territories. The exception is the Grevy's zebra. Stallions of this species mark out territories with urine and dung.

The mares, their foals, and immature males wander through as they wish. If food becomes scarce, though, the stallions leave their territories for a while and travel with the larger herds. During certain times of the year, these groups gather together to form loosely associated herds of up to several hundred, but the family groups still stay together within these larger groups. Zebras communicate with one another with facial expressions and sounds. They make loud braying or barking sounds and soft snorts and whuffs.

The position of their ears, how wide open their eyes are, and whether their mouths are open or their teeth are bared all mean something.

Ears flat back, for example, means trouble, or you better follow orders! You might see two zebras standing head to back, apparently biting each other, but they are really only nibbling on each other with their teeth to pull out loose hair and get a good scratch. Zebra foals have soft, fuzzy fur, and their stripes are usually brown and white at first. This is important, since the mare needs to move with the herd to find food and water. She cannot leave the foal behind, so it must be up and running quickly in order to stay with the family.

Foals must be able to recognize their mother from birth in order to survive. Mares usually do not adopt other foals, so there would be no chance of getting food from anyone but Mom. Mothers often separate from the herd a short distance so that their foals can imprint on them. Once the foal can readily identify its mother, the mare and her foal return to the herd for protection.

You'll find Robert holding court in the Park's Nairobi Station. With a wild population of about 25,, the mountain zebra is classified as threatened. Their numbers have now increased to several hundred, with the majority still in the national park.

The individual hairs in dark areas are intensely pigmented the whole way around. The team identified two variants of the gene or alleles called non-dun1 and non-dun2.

The latter form is more recent. When they compared modern horse genomes to 43,year-old horse DNA, they found that the Dun and non-dun1 alleles were already present in ancient horses — and they predate domestication.

The mutation was likely selected for by humans, and the more recent non-dun2 variant occurred after domestication. While Dun coloration provides camouflage for wild horses by making them less conspicuous, humans selected against camouflage in favor of more conspicuous colors.

Why Most Horses Lack The Dark Markings Of Their Ancestors | IFLScience

Primitive markings are a group of hair coat markings and qualities seen in several equine species, including horses , donkeys, and asses. In horses, they are associated with primitive breeds, [1] though not limited to such breeds. The markings are particularly associated with the dun coat color family. Other common markings may include horizontal striping on the legs, transverse striping across the shoulders, and lighter guard hairs along the edges of a dark mane and tail.

The dun coat and attendant primitive or "dun factor" markings reflect the wild type coat and are observed in all equine species. The last remaining true wild horse, Przewalski's horse , is also dun-colored with primitive markings. So, too, are horse breeds such as the Konik and the Heck horse , "bred back" to resemble the now-extinct tarpan , many of which are grullo or mouse dun in color. While no dun horse is without a dorsal stripe, primitive markings also sometimes occur on horses of other colors, particularly those with sooty characteristics and newborn foals.

While primitive markings are closely linked with the dun coat colors, the variations of expression and presence in non-dun horses suggest that the markings themselves may be governed by a separate genetic mechanism. Of equids other than horses, all except the mountain zebra show a distinct dorsal stripe. Among domesticated donkeys , most have a black dorsal stripe, though it can be difficult to see on melanistic individuals.

In Przewalski's horse, the dorsal stripe is usually dark brown, while it is black in the bred-back tarpan. In the plains zebra , the dorsal stripe is narrow and edged by white, while in Grevy's zebra , it is quite bold. The dorsal stripes of the onager and kiang are dark brown and especially vivid.

The dorsal stripe reflects the original coat color of the horse. Those on bay duns may be black or reddish, [4] while those on red duns are distinctly red. Dorsal stripes on dun horses with the cream gene seem unaffected by cream: smoky black -duns "smoky grullas" , buckskin -duns "dunskins" , and palomino -duns "dunalinos" have black, brown, or red dorsal stripes, as well. So-called "countershading dorsals", which are dorsal stripes occurring on non-dun horses, are a darker shade of the horse's coat color.

Also called zebra bars, tiger stripes, [5] or garters, leg bars are the most common accessory to the dorsal stripe. Leg bars on bay duns are black within the points, and reddish above them. Leg bars are prominent on Grevy's zebras and mountain zebras, and African wild asses also have well-defined black leg bars below the forearm and gaskin on a white or pale background.

However, as in horses, expression of leg bars seems to vary widely among donkeys, plains zebras, and Przewalski's horses, while they appear very seldom or not at all in onagers and kiangs. Leg markings may also take the form of blotches, patches, marbling, mottling, or spotting. The shoulder stripe is a transverse or "vertical" marking that usually crosses the withers and extends down the shoulders.

It is more marked in breeds closest to the wild African ancestors of the domestic donkey. Especially large markings are called neck or shoulder capes. Less common primitive markings include vertically oriented markings which may be arranged as bars, fine striping, or smudges. Such markings include:. The dorsal stripe runs through the mane and tail of a dun horse, so the center of the mane and tail are darker.

The outer edges may be significantly lighter, even close to white. These paler hairs are seen at the base of the tail and on the edges of the mane. The presence of guard hairs may also be called "frosting".

The presence of paler guard hairs on the mane and tail is seen throughout Equus. Less distinct primitive markings can also occur on non-dun horses, even in breeds which are not known to have any dun individuals. The most common primitive marking found is a dorsal stripe. This is because there are two types of non-dun, called non-dun1 and non-dun2. Non-dun 1 removes the diluting effect of dun, but keeps the primitive markings, while non-dun 2 removes both the diluting effect and the primitive markings.

Dorsal stripes and other primitive markings on non-dun horses are commonly called countershading dorsals. Primitive markings on non-duns can be seasonal, visible only when the horse is shedding its coat. Many foals , particularly if they are buckskin , smoky black , or black , are born with primitive markings such as dorsal stripes and leg bars that disappear after the foal coat sheds. Such horses are sometimes mistakenly registered as dun. This error seems particularly common in foals that turn gray.

From Wikipedia, the free encyclopedia. A countershading stripe, such as on this bay horse, is not considered a primitive marking in the same sense as those on asses or dun-colored horses.
