The black rhinoceros (or Diceros bicornis), also known as the hook-lipped rhinoceros, is a large ungulate native to the grasslands and scrublands of Southern and Eastern Africa. Black rhinos have two horns on their face, with the anterior horn being much longer than the posterior horn. They have thick, grey skin, stocky limbs, small eyes, and oval-shaped ears. The black rhinoceros stands 1.40m to 1.80m tall at the shoulder, is 3m to 3.75m long, and weighs between 800kg and 1400kg. Males and females are similar in size.

The African crested porcupine (or Hystrix cristata) is a large species of rodent found in the semi-deserts, savannahs, and montane areas of Central and Northern Africa, as well as Italy. Its coarse, bristled fur is dark brown to black in colour, with its most distinctive feature being the black and white quills that grow from the middle of its neck, across its back and sides, and down its tail. These quills are raised upright when the porcupine feels threatened, and are very sharp. The African crested porcupine has a blunt, rounded snout, small eyes, and round ears.

The addax (or Addax nasomaculatus) is a species of antelope that lives in remote areas of the Sahara Desert. Having historically lived throughout North Africa, they are now only found in areas in Niger and Chad. The addax is cream, white, or sandy in colour, with brown markings around the face and muzzle. Both sexes have dark, twisted horns, which is why they are sometimes called screwhorn antelope. Addaxes can achieve a body length of 1.20m to 1.30m. Males are usually taller and heavier than females, standing 1.05m to 1.15m tall at the shoulder and weighing 100kg to 125kg.
