Facts You Might Not Know About Gazelles

Gazelles are well-known members of the antelope family and are especially recognized for their impressive speed. They mainly inhabit dry, open environments such as grasslands and deserts. Many species live in migratory or nomadic groups, constantly moving through their surroundings while feeding on grasses and shrubs and remaining alert for predators.

Most gazelles have tan or sandy-colored coats that help them blend into their arid surroundings. They are common across dry regions of Africa and Asia, but their camouflage can make them surprisingly easy to overlook. A gazelle may appear to be nothing more than part of the landscape until the sudden appearance of a predator sends it racing away. Here are several fascinating facts about these graceful animals, including some of the challenges they face as human activity increasingly overlaps with their habitat.

1. Gazelles Escape Cheetahs by Outmaneuvering Them

Gazelles are extremely capable runners. Thomson's gazelles can reach approximately 43 mph, or 70 kph, while some other species have been recorded at speeds approaching 60 mph, or 100 kph. That is more than twice the fastest recorded speed of a human runner, with Usain Bolt reaching about 27 mph, or 43 kph. However, even these remarkable speeds cannot always match a cheetah, which can accelerate to around 75 mph, or 120 kph.

Instead of attempting to beat a cheetah in a straight-line race, gazelles often rely on sharp turns and stamina. By repeatedly forcing the cheetah to change direction, a gazelle can reduce some of the predator's speed advantage. This strategy is not without danger when the chase is close, but endurance can provide an important advantage. Cheetahs can maintain their top-speed sprint for only about 0.28 miles, or 0.45 kilometers, while gazelles are capable of sustaining fast movement for much longer. If the gazelle can remain out of reach long enough, the cheetah may eventually have to abandon the pursuit.

2. Pronking May Send a Message to Predators

When escaping a predator, gazelles sometimes perform a distinctive leap in which all four legs become relatively stiff and the animal springs vertically into the air. This behavior is called “pronking” or “stotting.”

At first, the behavior seems counterproductive. Jumping high makes the gazelle more noticeable, while the repeated leaps also consume energy and may appear to slow its escape. Scientists have proposed several explanations, including the possibility that pronking warns other herd members about danger or helps prevent a predator from launching a surprise attack from tall vegetation.

Studies of Thomson's gazelles, however, indicate that these leaps may actually be a form of communication directed toward predators. Pronking could act as what evolutionary biologists call an “honest signal,” with the gazelle demonstrating its physical condition and suggesting that it would be difficult to catch. This may cause the predator to give up before investing energy in a lengthy chase.

Pronking may also communicate that the gazelle has already detected the predator, removing the element of surprise. In young gazelles, the behavior may serve another purpose as well: a calf may use it to signal its mother that it is in danger and needs protection.

3. Some Gazelles Can Reduce the Size of Their Hearts and Livers

Gazelles have numerous adaptations that help them survive in extremely dry environments. During severe droughts, however, even these specialized animals can struggle when food and water become scarce.

Certain species have developed physiological adjustments that help them cope with these difficult periods. Sand gazelles, for example, can reduce the size of organs such as the heart and liver that require significant amounts of oxygen. With smaller oxygen-demanding organs, they can lower their breathing rate and potentially decrease the amount of water lost through evaporation during respiration.

4. Gazelles Inspired an Ancient Poetry Tradition

The English word “gazelle” may have entered the language through French, but its deeper origin is generally linked to the Arabic word ghazaal, meaning deer or gazelle. The word shares its root sounds with ghazal, a term that can be interpreted roughly as “conversations with women.” These related Arabic words may have contributed to the name of a traditional poetic form known as the ghazal.

The ghazal dates back to at least the sixth century and commonly explores romantic love, separation, longing, and emotional loss. A traditional ghazal consists of pairs of lines, with the second line of each couplet ending in the same word or phrase, preceded by a rhyming word.

The melancholy quality associated with the form has been connected to the pain of unfulfilled love. This meaning may also relate to another interpretation of ghazaal, referring not simply to a deer or gazelle but specifically to the sorrowful cry of a wounded deer.

5. Some Gazelles Make a Honking Sound When Alarmed

Gazelles communicate through a surprisingly broad selection of sounds. Depending on the species and situation, they may produce snorts, grunts, bleats, bellows, and other vocalizations.

The dama gazelle of north-central Africa has an especially unusual alarm call. According to the Smithsonian Conservation Biology Institute, it can produce what has been described as an appealing “honk” when it encounters something that causes concern.

The sound can differ in both pitch and duration, and individual dama gazelles have distinctive voices, meaning that each animal can sound somewhat different from the others.

6. Female Gazelles Have Horns Too

In many deer species, only males grow antlers, but gazelles are different. Both male and female gazelles can develop horns, although those belonging to males are often longer.

Gazelle horns consist of a bony center covered by an outer layer made primarily of keratin. They are commonly curved and feature noticeable rings along their length. Unlike deer antlers, which are shed and regrown each year, gazelle horns remain permanently attached to the animal.

7. Young Males Often Live in Bachelor Herds

Gazelles are generally social animals and frequently gather in groups. Some herds can contain hundreds of individuals, while others are considerably smaller. Their social groups may also be separated according to sex.

Among Thomson's gazelles, females form migratory groups and may move into territories controlled by males, particularly when those territories contain valuable resources such as plentiful food, water, and shade.

Young males that have not yet established territories often gather together in groups known as bachelor herds. Territorial adult males prevent these younger males from entering the areas they control.

Bachelor herds tend to remain toward the outer edges of gazelle-populated regions. Because of their position around the periphery, these groups may be among the first gazelles encountered by predators.

8. Several Gazelle Species Are Facing Serious Declines

A number of gazelle species are currently experiencing significant conservation problems. Many are classified as at least vulnerable, while others face even more severe threats. Unsustainable hunting has contributed to population declines in several species, while habitat destruction and competition with livestock for food have added further pressure.

The dama gazelle is one of the most seriously affected species. The International Union for Conservation of Nature classifies it as Critically Endangered and estimates that only around 100 to 250 individuals remain in the wild.

With such a small wild population, captive-breeding efforts may now represent one of the most important opportunities for maintaining the species and preventing its complete disappearance.
