Species and Subspecies
Gazelles belong to the genus Gazella, which encompasses over a dozen species, though some classifications also include Eudorcas and Nanger species. Among the most well-known are Grant’s gazelle (Nanger granti), Thomson’s gazelle (Eudorcas thomsonii), and the mountain gazelle (Gazella gazella).
These species vary in size and habitat preferences. For instance, Grant’s gazelle is larger and more commonly found in open grasslands, while the smaller Thomson’s gazelle prefers short grass plains and often associates with larger herbivores for protection. The mountain gazelle, as its name suggests, inhabits more rugged terrain in the Middle East and can tolerate drier conditions than its counterparts.
Description
Gazelles are medium-sized antelopes with a slim, lightweight build, perfectly adapted for running at high speeds. They typically range in size from 2.3 to 4.5 feet (70 to 135 cm) in body length, depending on the species, and weigh between 26 and 165 pounds (12 to 75 kg). Their coat is generally light brown or tan, with white underbellies and striking black markings, such as stripes or patches on their flanks and faces.
A distinctive feature of most gazelle species is their slender, ringed horns, which can vary in length. Both males and females may have horns, though the males’ are usually longer and more curved. These horns play a crucial role in displays of dominance, especially during the breeding season. Gazelles also have large, dark eyes, which help them detect movement and spot predators from a distance.
Sexual dimorphism is evident in many gazelle species, with males being larger and sporting more prominent horns. Females, while smaller and lighter, are still agile and capable of reaching impressive speeds, helping them to evade predators in open terrain. Gazelles are known for their incredible running ability, capable of reaching speeds up to 60 miles per hour (97 km/h) in short bursts, making them one of the fastest animals on the planet.
Habitat and Distribution
Gazelles are predominantly found across the African continent, particularly in East Africa, where vast savannas and grasslands provide the ideal habitat for these animals. They also inhabit parts of the Middle East and Central Asia, where species like the goitered gazelle (Gazella subgutturosa) and the Arabian gazelle (Gazella arabica) thrive in arid, desert-like environments.
Gazelles are adapted to live in a variety of habitats, from dry deserts to lush grasslands. Some species, such as the Thomson’s gazelle, prefer areas with short grasses, where they can graze easily and spot predators.
Others, like the mountain gazelle, are more suited to rocky, elevated terrains where vegetation is sparse. Despite their varying habitat preferences, all gazelles share an ability to withstand harsh conditions and long periods without water, drawing moisture from the plants they eat.
Behavior
Gazelles are diurnal animals, most active during the day, particularly in the early morning and late afternoon when temperatures are cooler. They spend much of their time grazing, and their agility and speed allow them to cover large distances quickly in search of fresh grass and safe resting areas.
Socially, gazelles typically live in herds, which can vary in size depending on the season and the availability of food. Some herds consist of females and their young, while others are bachelor groups of males.
During the breeding season, male gazelles become highly territorial and use their horns in displays of dominance and competition for females. These confrontations can involve aggressive posturing, chasing, and sometimes head-butting contests. Outside of the breeding season, however, gazelles are generally peaceful and focus on feeding and avoiding predators.
Communication among gazelles includes visual signals such as head movements and body posture, as well as vocalizations like snorts and bleats. When alarmed, gazelles use a behavior known as “stotting” or “pronking,” where they leap into the air with stiff legs. This serves as a signal to others in the herd of approaching danger, while also confusing predators with erratic movements.
Diet and Feeding Behavior
Gazelles are herbivores, and their diet consists primarily of grasses, leaves, shoots, and shrubs. In drier environments, they can also feed on hardy desert plants, extracting moisture from the vegetation to survive in arid conditions. They are selective feeders, often preferring nutrient-rich grasses, but they are also opportunistic, eating what is available when resources are scarce.
These antelopes are ruminants, meaning they have a specialized stomach with multiple chambers that allow them to digest tough plant material more efficiently.
They often graze in the cooler parts of the day to conserve water and energy, seeking shade during the hotter midday hours. Gazelles play an important role in their ecosystems by helping to manage grass growth and prevent overgrazing in areas they inhabit.
Although gazelles do not hunt, they must be constantly vigilant against the threat of predators. Their impressive speed and agility are their main defense mechanisms, allowing them to escape danger quickly, often using zigzagging motions to evade chasing predators like cheetahs and lions.
Predators
Gazelles face a number of natural predators, with the most notable being cheetahs, lions, leopards, and hyenas. Cheetahs, in particular, are well-known for their ability to match the gazelle’s speed in short bursts, though gazelles often rely on their endurance and evasive maneuvers to escape. Lions and leopards may ambush gazelles, using stealth rather than speed to catch their prey.
In addition to these large predators, gazelles must also be wary of smaller carnivores like jackals, as well as birds of prey that target young or injured individuals. Gazelle calves are especially vulnerable during their first few months of life and rely on their mothers and the protection of the herd to survive.

Gazelles typically breed once a year, with mating seasons varying depending on the species and location. During the rut, males establish territories and compete for the attention of females through displays of strength and dominance. Males will fight with their horns to win over mates, and the strongest males will have the opportunity to breed with multiple females.
After a gestation period of around 5 to 6 months, females give birth to a single calf, though twins are occasionally born. The newborns are hidden in tall grass or secluded areas for the first few weeks of their lives, where they remain motionless to avoid detection by predators. The mother will return periodically to nurse them until they are strong enough to join the herd.
Gazelle calves grow quickly and are able to run within hours of birth, a crucial adaptation for survival in predator-rich environments. They are weaned after a few months and reach sexual maturity within their first year of life. Despite the dangers they face as juveniles, gazelles that survive their early years can live up to 10-15 years in the wild.
Conservation and Threats
The conservation status of gazelles varies by species, with some populations thriving and others facing significant threats. For example, Thomson’s gazelle and Grant’s gazelle are listed as “Least Concern” by the IUCN, with stable populations across their ranges.
However, species like the dama gazelle (Nanger dama) and the goitered gazelle (Gazella subgutturosa) are classified as “Endangered” or “Vulnerable” due to habitat loss, hunting, and competition with livestock.
Gazelles are particularly vulnerable to habitat destruction caused by agriculture and human expansion, which reduces their grazing areas and brings them into closer contact with humans. In some regions, gazelles are hunted for their meat, horns, or hides, further threatening their populations. Climate change, which impacts water availability and vegetation growth, also poses a long-term risk to gazelle habitats.
Conservation efforts for gazelles include the establishment of protected areas such as national parks and wildlife reserves, where they can live with minimal human interference. Anti-poaching initiatives and community-based conservation programs are also vital in helping to safeguard the future of these iconic animals.
Fun Facts
- Gazelles can reach speeds of up to 60 miles per hour (97 km/h) in short bursts, making them one of the fastest animals on Earth, only slightly slower than cheetahs.
- Despite their impressive speed, gazelles often rely on zigzagging movements to escape predators rather than running in a straight line, which helps confuse their attackers.
- Gazelles are known for their “stotting” behavior, where they jump high into the air with stiff legs to warn others of danger or to show their fitness to predators.
- Gazelles have excellent vision, allowing them to detect predators from a great distance. Their large eyes are positioned on the sides of their heads, giving them a wide field of view.
- Some species of gazelles, like the Grant’s gazelle, can survive for long periods without drinking water, as they can extract moisture from the plants they eat.
