Zebra Basics
Zebras are more than just horses with stripes.
Each stripe pattern is unique, almost like a fingerprint, and scientists have a number of theories about why they evolved.
Physical Characteristics
Zebras are distinguishable by their black and white stripe pattern that’s unique to each individual.
The function of these stripes may range from camouflage to pest repellent.
Their coat is made up of fur that helps to regulate their temperature in the African sun.
An adult zebra’s size can vary, but they typically stand about 1.3 to 1.5 meters at the shoulder and can weigh anywhere from 200 to 450 kilograms, depending on the species.

Tail: The tail of a zebra has a tuft of hair at the end which they use to swat away flies and other pests.
-
Stripe Pattern: No two zebras have exactly the same stripe pattern.
Scientists believe that the stripes help to confuse predators when zebras are grouped together.
Species and Subspecies
Zebras fall into three main species: the plains zebra (Equus quagga), mountain zebra, and the Grévy’s zebra.
Each species has its own set of stripe patterns and habitat preferences.
-
Plains Zebra (Equus quagga): The most common zebra species, distinguished by stripes that are bolder and more spread out.
-
Mountain Zebra: Generally smaller and have narrower stripes than the plains zebra, live in mountainous and rocky environments.
Both species show remarkable adaptability to their environments, but various subspecies of zebras are facing threats from habitat loss and hunting.
Habitat and Diet
Zebras are synonymous with the wild landscapes of Africa, where they roam the grasslands and savannas in search of food and water.
Their patterns of habitat occupation and feeding are closely intertwined with their survival and the ecosystems they inhabit.
Zebra Habitats
Zebras are predominantly found in Africa’s vast grasslands, particularly in the savannas, where they have abundant space for grazing.
Each species of zebra has distinct habitat preferences, with the Cape Mountain zebra favoring more mountainous regions in southern Africa, as captured in their habitat utilization in the Bontebok National Park.
This region is known for its dystrophic fynbos habitat, where zebras show seasonal patterns in their habitation.
On the other hand, the zebras in the Mountain Zebra National Park display different movement patterns, which are likely in response to the availability and quality of food sources across various terrains.
These animals rely heavily on specific sectors and habitat types within their ranges, which can change seasonally, highlighting the dynamic nature of their existence within these protected areas.
Feeding Patterns
As herbivores, zebras primarily graze on grasses, making fresh grass and hay staples of their diet.
Their feeding habits are driven by the necessity to consume a high quantity of forage to meet their energy requirements.
The composition of their diet can be influenced by the nutrient levels in the grasses they consume, which in turn is connected to soil fertility.
The foraging behavior of both zebra and wildebeest in the savannas has been associated with the nutrient levels, specifically nitrogen (N) and phosphorus (P), present in their food sources.
Seasonal movements of the Cape mountain zebra are also thought to be affected by variations in the protein content of their diets, as indicated by the study of their faecal matter, pointing to a selective feeding strategy that aims to maximize their nutritional intake across different seasons.
Access to water is another significant factor in the feeding patterns of zebras; they need to drink regularly and will often be found grazing in areas where fresh water is available.
The balance between their need for food and water shapes their daily and seasonal movements, ensuring that they can thrive in their natural habitats.
Social Structure and Behavior
Zebras are social animals that live in groups known as herds.
Within these herds, there is a fascinating hierarchy and family structure.
The typical herd consists of a dominant stallion (the adult male), several mares (adult females), and their foals (young zebras).
Each herd operates like a tight-knit family group.
The stallion’s role is to protect the mares and foals from predators and other stallions.
Meanwhile, the mares often take a collaborative approach to care for the young.
Surprisingly, not all zebra families are permanent; some exhibit a more fluid social structure, with members joining or leaving the group.
Zebras communicate with one another through an array of facial expressions and sounds, which can be as nuanced as the stripes on their skin.
The stripes themselves are unique to each zebra, much like human fingerprints.
These distinct patterns create strong visual bonds among the members of the herd.
In some species of zebra, such as the plains zebra, there’s a looser structure: groups called ‘harems’ that feature one stallion with several mares and their recent offspring.
These harems may come together with others to form super herds during migrations or when grazing on the savannah, demonstrating the adaptability and sociable nature of zebras.
