Antelopes are even-toed, hoofed mammals found primarily throughout Africa and Asia. They belong to the Bovidae family, which also includes cattle, sheep, and goats, but antelopes are distinct. The term describes a collection of about 91 species that share certain characteristics yet vary dramatically in appearance and size. This diversity allows them to inhabit environments ranging from dense forests to open savannas and arid deserts.
General Body Structure and Build
The overall silhouette of an antelope is one of athletic grace, built for speed and agility. Most species possess a lean, muscular build supported by long, thin legs designed to facilitate powerful strides. This physique allows them to cover ground rapidly and make sudden changes in direction to evade predators.
Their feet end in cloven hooves, which provide stability and traction across various terrains. The neck is typically long, holding a refined, wedge-shaped head. A common feature is the presence of large eyes set far back on the head, granting them an extensive field of vision to detect threats.
The size range among antelopes is vast. The smallest species, the Royal Antelope, stands only about 10 inches tall at the shoulder, weighing as little as four pounds. Conversely, the Giant Eland can reach a shoulder height of six feet and weigh nearly a ton.
The Defining Feature: Horns
A defining characteristic of antelopes is the presence of horns, which are structurally different from the antlers found on deer. Antelope horns are permanent fixtures that grow continuously throughout the animal’s life and are never shed. Each horn consists of a bony core extending from the skull, covered by a thick, unbranched keratin sheath.
These structures are used for defense against predators and for display during social interactions, especially in male competition for mates. Horns present a wide variety of shapes across species, appearing straight on the Oryx, lyrically curved on the Impala, or spiraled on the Greater Kudu. While both sexes in many species possess horns, they are often larger and more robust in males, a feature known as sexual dimorphism.
Diverse Coats and Markings
Antelope coats serve the dual purpose of providing camouflage and assisting with heat regulation. Coloration is diverse, primarily consisting of pale tans, grays, rich browns, and russets. This coloring often matches the dry grasses and scrub of their savanna habitats, allowing them to blend into the background.
Many species feature distinct markings that break up the body’s outline or serve as visual signals. Forest-dwelling species like the Bongo have striking white stripes across a red-orange coat, helping them disappear into the dappled light. Other antelopes, such as the Gemsbok, possess vivid black-and-white facial masks. Specialized markings, like the white rump patch on the Springbok, become highly visible during flight, potentially acting as a warning or a follow-me signal for the herd.
