Antelopes can be very big or very small. Some are large and heavy. Others are tiny.

It is fun to learn about them!
Antelopes are a large group of animals. 
Antelopes can be very big or very small. A male eland is very heavy. A royal antelope is tiny. Most have short fur. Many are brown with white bellies. Some have stripes on their backs.
Antelopes have horns. These are different from deer antlers. Antlers fall off every year. Antelope horns grow all the time. They are made of bone and keratin. Keratin is the same stuff in your hair. These horns never fall off.
Many antelopes are very fast. They run to stay safe from danger. A Thomson's gazelle can run very fast. It can reach speeds of 97 km/h. Some can also jump high. An impala can jump 2.4 meters into the air.
Antelopes are many different kinds of living things. They belong to a large family called Bovidae. This family also includes goats, sheep, and cattle. Most antelopes live in Africa, but you can find them in India and the Middle East too. Some live in Central Asia and parts of Russia. There are about 91 different species of antelope. They live in many places like hot deserts and cold areas. Some even live in forests or near water.
These animals have many ways to stay safe. Most antelopes use speed to escape from danger. They have special muscles that help them run fast. Some muscles help with quick bursts of speed. Other muscles help them run for a long time. This lets them follow the rain to find new grass. Many species move in huge groups during long trips. This is called migration.
People have known about these animals for a long time. The English word "antelope" first appeared in the year 1417. It comes from Old French and Latin words. One old story says the name came from a Greek word for "beautiful eye." This might be because of their long eyelashes. In the year 1607, the word was used to describe living animals. 
Antelopes come in many shapes and sizes. A male common eland is huge and heavy. A royal antelope is very small. Most have short fur that is brown or white. Some have stripes on their backs. 
Many people mistake antelopes for deer. They are actually not very close relatives. Deer and antelope often live in similar places. They both eat plants and use the same habitats. This can lead to competition for food. In some places like India, they stay in their own areas. This helps them live together without fighting for the same resources. 
Antelopes are a diverse group of animals belonging to the family Bovidae. This family also includes cattle, sheep, and goats. While many people call them "antelope," they do not form one single biological group. Some species are more closely related to goats than to other antelopes. A specific group called the "true antelopes" includes only the genera Gazella, Nanger, Eudorcas, and Antilope. In North America, the pronghorn is often called the "American antelope." However, the pronghorn actually belongs to a different family called Antilocapridae.
One major way to identify an antelope is by its horns. Unlike deer, which grow bony antlers that fall off every year, antelopes have permanent horns. These horns consist of bone encased in a tough layer of keratin. Keratin is the same protein found in human hair and nails. Because these horns grow steadily, they never fall off. If a horn breaks, it may stay broken or take many years to partially grow back.
Antelopes live in many different environments across the globe. Most species are native to Africa, where they live in savannahs. In East Africa, between 25 and 40 different species may live in the same area. Other species live in the deserts of the Arabian Peninsula or the cold regions of Central Asia. Some species are specialized for specific habitats. For example, the Arabian oryx lives in the desert, while the saiga lives in extreme cold. Others, like the forest antelope, live in more secluded areas.
The history of the word "antelope" stretches back many centuries. The English word first appeared in 1417. It comes from the Old French word "antelop," which came from Medieval Latin. Some believe the name derives from the Greek word "anthos," meaning flower, and "ops," meaning eye. This might suggest a "beautiful eye" or refer to their long eyelashes. In the year 1607, the term began to be used specifically for living, deer-like animals.
Physical traits among antelopes vary significantly in size and color. A male common eland is very large and heavy. In contrast, an adult royal antelope is quite small. Most antelopes have short fur that is brown or white. Some species, like the zebra duiker, have stripes or unique patterns. Many gazelles have white rumps that flash a warning to other animals when they run. The springbok has a unique patch of white hair on its back that stands up when it senses danger.
Speed and jumping are essential for an antelope's survival. Many species use high-speed running to escape predators. Their muscles are specially designed for these movements. Some have high concentrations of glycolitic fast-twitch type IIx muscle fibers for quick bursts. For example, the springbok has a 58% concentration of these fibers. Other species, like the impala, have muscles built for high endurance. This allows them to maintain speed over longer distances.
Antelopes are incredibly fast and agile athletes. A Thomson's gazelle can reach speeds of 90 to 97 km/h when escaping a lion. The pronghorn in North America can also reach 97 km/h on flat ground. Even the saiga antelope has been clocked at 80 km/h. Their limbs are also built for efficiency. Antelopes often have very long limbs relative to their body mass. This helps them maintain high speeds for longer periods of time.
Finally, antelopes play a vital role in their ecosystems through migration. Many plains species move in large groups to follow the rains. This helps them find fresh grass to eat. These mass migrations, such as those performed by gnus and gazelles in East Africa, are some of the largest in the mammal world. By moving across the landscape, they connect different habitats and help manage the vegetation they consume.
