Addax

The addax, also known as the white antelope or screwhorn antelope, is a spiral-horned antelope. Despite being indigenous to the Sahara Desert, owing to unregulated hunting, just a handful survive in the wild. As a result, the IUCN has classified them as Critically Endangered, and the majority of the surviving individuals currently live in zoos or preserves. Males typically stand 41 to 45 inches tall and weigh 220 to 276 pounds, while females are shorter. The color of their coat changes throughout the year, from gray-brown in the winter to white or blonde in the summer.

The addax is still on the list of the largest horned animals in the world, despite being on the verge of extinction. Both males and females develop horns, which they bend in and out with one to two loops. Male horns may grow up to 43 inches long, while female horns are normally 22 to 31 inches long.
