The addax, also known as the white antelope or screwhorn antelope, is a large mammal that is well adapted to living in desert regions. It has a compact body, long legs, and distinctive twisted horns that can reach up to 3 feet in length. The addax has a pale coat with a tuft of hair on its forehead and a hump of fat on its back, which helps it store water in its body. It is a critically endangered species, facing threats such as habitat loss, hunting, and climate change, which have resulted in a severe decline in its population. Conservation efforts are underway to protect and preserve this unique and rare antelope species.
