The saiga antelope (or Saiga tatarica) is a bovid living on the steppes and grasslands of Mongolia, Kazakhstan, Turkmenistan, Uzbekistan and Russia. It is tan in colour, with a pale underside, and has large eyes and rounded ears. The distinctive large nose has broad, mobile nostrils, which is larger in males. Males are also generally built larger and heavier than females, and carry upright, pale, and slightly translucent horns, which are 28cm to 38cm long. They stand 67cm to 81cm tall at the shoulder, are 1.1m to 1.4m long and weigh between 26kg and 69kg.

The mute swan (or Cygnus olor) is a large waterfowl that lives throughout Europe and Asia, with invasive populations in North America and Japan. It is white, with black feet and an orange-red bill, and black markings around the nostrils, eyes, as well as the edge and tip of the bill. A leucistic morph can occur, which is almost indistinguishable in adults, where the legs have a pink colour instead of black. Juvenile swans are normally grey, but have a white plumage if exhibiting leucism. Mute swans have a distinctive black basal knob on the root of the beak between the eyes.

The wisent (or Bison bonasus), also commonly referred to as the European bison, is a large ungulate living in the forests and meadows of Poland, Russia, Belarus, Lithuania, Ukraine, and Slovakia, in Eastern Europe. Wisents are characterised by their large head, shoulder hump and forequarters, all of which are covered in a brown, shaggy coat. The hindquarters are less bulky and are covered in a thinner coat. Both males and females have curled horns that point inwards towards the head and look otherwise alike, though males are larger by about 5%.

The wild boar (or Sus scrofa), also known as the Eurasian wild pig, is a pig native throughout the temperate regions of Eurasia, as well as Mediterranean Northern Africa, Asian deserts and shrublands, and tropical rainforests and grasslands of Southeast Asia. It has also been introduced to North and South America and Oceania. Due to its wide distribution and adaptability, there are 16 recognised subspecies of the wild boar, varying greatly in appearance. The largest wild boars live in Central and Eastern Europe.

The takin (or Budorcas taxicolor) is a large goat-antelope living in the montane regions of Tibet, Bhutan, Northern India, Myanmar, and China. Takins have a stocky, cow-like build and are covered in shaggy fur. There are four subspecies of the takin, which vary in coat colouration and size. Legs are often darkened, to nearly black, while the overall colouration ranges from marbled black-brown to grey-yellow to golden. Males are larger than females, but both sexes have horns that measure up to 64cm in length.
