Zebras: Important facts to know about species, habitats, behavior, purpose behind black and white stripes and more

zebras They are striking equine mammals distinguished by their iconic black-and-white striped fur. Native to the grasslands and savannas of Africa, these animals are closely related to horses and donkeys but have unique characteristics that differentiate them. There are three main species: Plains zebra, Grevy’s zebra, and Mountain zebra, each with their own unique characteristics and behaviors. Zebras play an important role in their ecosystems, and their social structure and migratory habits attract the attention of wildlife enthusiasts and conservationists.
However, they face serious threats such as habitat loss and poaching, making it vital to understand and protect these extraordinary animals to preserve Africa’s rich biodiversity. Zebras belong to the Equidae family, characterized by an odd number of toes, and are part of the order Perissodactyla, which also includes rhinos and tapirs.

zebra species

There are three main species of zebra living in the wild:

  • Grevy’s Zebra (Equus grupyi)

Grevy’s zebras are the largest of the zebra species and are recognized by their narrow stripes that are closer together than other zebras. They are classified as Endangered due to habitat loss and hunting. They live mainly in the dry grasslands and savannahs of northern Kenya and parts of Ethiopia.

  • Mountain Zebra (E. zebra)

This species has two subspecies: the Mount Hartmann Zebra and the Cape Mountain Zebra. Mountain zebras have a unique dewlap and grid-like stripe pattern. They are adapted to mountainous regions and are classified as Vulnerable. Hartmann’s subspecies is more common in Namibia, while the Cape mountain zebra is found in South Africa.
The plains zebra is the most widespread species, known for its wide habitat in southern and eastern Africa. It is characterized by broader stripes that are less distinct than those of the Grevy’s zebra. This species has many subspecies, but recent DNA studies suggest that traditional subspecies classifications may need revision. The plains zebra is classified as Near Threatened due to habitat encroachment and poaching.

Zebra habitat and distribution

Zebras live mainly in the grasslands and savannahs of southern and eastern Africa. Their preferred environments are treeless plains where they can graze on grasses and other plants. Unfortunately, habitats are decreasing due to agriculture, urbanization and climate change. Zebras are extinct in countries such as Lesotho and Burundi and are vulnerable to habitat changes brought on by climate change, making them susceptible to drought and habitat fragmentation.

Zebra’s physical characteristics

Zebras are often recognized by their stripes, which vary between species and individuals. Each zebra has a unique pattern that resembles a human fingerprint. Ribbons serve several potential functions:

  • Thermoregulation: Black stripes absorb heat while white stripes reflect, creating cooling air currents that help regulate body temperature in hot environments.
  • Camouflage: The patterns may help zebras blend into tall grass and confuse predators, especially since their primary predators, lions, are colorblind.
  • Pest deterrence: Recent research suggests the strips may help repel biting flies and other insects that can transmit diseases.

Zebra’s behavior and social structure

Zebras are social animals, often found in groups known as herds or herds. These groups usually consist of family units led by a dominant male who mates with multiple females. Social structure can differ significantly between species:

  • Plains and mountain zebras: They tend to have a more structured society, with harems consisting of one man and several women. These family units maintain a hierarchy, and members look out for each other, especially in the face of predators.
  • Grevy’s zebra: This species has a more fluid social structure where individuals can move around in larger groups that are less stable.

Zebras are known for their strong maternal bonds. Mothers protect their foals, often keeping them close and training them in social interactions and grazing.

How do zebras communicate?

Zebras use a variety of sounds to communicate:

  • Braying: Similar to donkeys, zebras can bray to communicate over long distances. Their brays range from low growls to high-pitched squeals, and they often use this sound to find mates or other members of the herd.
  • grunts: Like horses, zebras growl when excited and make soft whistling sounds when greeting each other.
  • barking: They can produce high-pitched barks to warn others in the flock of potential danger.

Do zebras migrate?

One of the most remarkable behaviors of zebras is their annual migration. Plains zebras participate in a major migration with other ungulates, traveling nearly 2,800 miles between the Serengeti in Tanzania and the Masai Mara in Kenya in search of food and water. This migration is not only vital to their survival, but also plays an important role in the ecosystem as they graze on grasses and help manage plant growth.

Conservation status of zebras

Zebras face various threats, especially human activities. The Grevy’s zebra is classified as Endangered due to poaching and habitat loss, while the mountain zebra is classified as Vulnerable. The plains zebra is considered Near Threatened due to declining populations in certain areas.
Conservation efforts are ongoing in various regions, focusing on habitat protection, anti-poaching measures, and education to reduce human-wildlife conflict. Protected areas and wildlife reserves play a critical role in maintaining zebra populations.

How fast can a zebra run?

Zebras are incredibly fast creatures that can reach speeds of up to 65 km/h (about 40 mph) when galloping across the African plains. This extraordinary speed allows them to escape predators such as lions. Interestingly, zebra foals can join the herd and run alongside their mothers just a few hours after birth.

How do zebras stay cool in the sun?

Zebras have a unique adaptation that helps them regulate their body temperature in the scorching African sun. Their distinctive striped coating is believed to dissipate more than 70% of incoming heat. This is because air moves at different speeds over the black and white stripes; Black lines absorb heat while white lines reflect it. As a result, zebras create their own cooling air currents, allowing them to stay comfortable even in high temperatures.

Purpose of zebra stripes

Zebra stripes serve many purposes:

  • Camouflage: The stripes help zebras blend into their environment, especially in tall grass, making it harder for predators to spot them. Since lions are colorblind and see shades of black and white, a herd of running zebras creates a confusing visual effect, helping them escape.
  • insect deterrent: Recent research suggests that the monochrome stripe pattern may impair the vision of biting insects such as flies, making zebras less attractive targets.

Are zebras white with black stripes?

Contrary to popular belief, zebras are black with white stripes. Although the white bellies of some zebras lead to the misconception that they are white with black stripes, studies based on embryological evidence confirm that the basic color of zebras is black and that white stripes develop on top.

What do you call a group of zebras?

A group of zebras is often referred to as a “dazzle”. This term refers to the visual chaos created by a group of zebras in motion. Other less popular terms include herd or enthusiasm of zebras.

Are zebras social animals?

Zebras exhibit social structures that vary by species:

  • Grevy’s zebras: These zebras tend to have more open social structures.
  • Plains and mountain zebras: They live in close-knit groups called harems, usually consisting of a dominant male and up to six breeding females with their young. Every woman has a designated rank in the social hierarchy.

In case of danger, if a zebra is injured by a predator, other members of the herd will form a protective circle around the injured individual to ward off the threat using their teeth and hooves.

Do zebras sleep on their feet?

Similar to horses, zebras often sleep standing up and only do so when in the safety of a group. This behavior keeps them alert for potential threats.
