Antelope

Not actually one animal

“Antelope” is a catch-all term rather than a taxonomic group — it describes any bovid that isn’t a sheep, goat, cow, or buffalo. The 90+ species range from the rabbit-sized royal antelope (4 kg) to the giant eland (over 900 kg). Most are African.

The North American pronghorn (Antilocapra americana) is widely called an “antelope” but isn’t one taxonomically — it’s the only surviving member of an entirely separate family, the Antilocapridae.

Speed and evasion

Many antelope are built for sustained running:

• Pronghorn — second-fastest land mammal at 88 km/h; uniquely able to maintain high speeds for extended distances. Evolved to outrun an extinct American cheetah.
• Springbok — capable of pronking (stiff-legged jumping bursts) and sustained sprints over open veld.
• Thomson’s gazelle — 80 km/h; the African cheetah’s primary prey.
• Sable antelope — large, powerful, defensive runners.

Speed is generally an antiprey adaptation; antelope evolved alongside fast predators.

Iconic herds

The annual Serengeti-Mara migration moves around 1.5 million wildebeest (a type of antelope) and 200,000 zebra in a circular route between Tanzania and Kenya — the largest mammal migration on Earth. The crossings of the Mara River, where crocodiles wait, are among the most-photographed wildlife events anywhere.

Conservation paradox

Antelope conservation is mixed:

• Some species are abundant — common impala, springbok, blackbuck.
• Others are critically endangered — saiga (steppes of Kazakhstan), addax (Sahara), hirola (Kenya), bontebok (South Africa, recovered from near-extinction).

Habitat loss, hunting pressure, and disease outbreaks (saiga have suffered mass die-offs from bacterial infections) drive the most threatened species toward extinction even as common species thrive.
