Hermann’s tortoise (or Testudo hermanni) is a small species of tortoise that is found throughout the coastal forests of the Mediterranean. The carapace is patterned in yellow and black and varies based on the subspecies and by individual. The Eastern subspecies is much larger than the Western, reaching sizes of up to 28cm long, compared to 18cm long. Females are generally larger than males in this species. Depending on their size, Hermann’s tortoises can weigh between 2kg and 4kg.

A large mustelid, the wolverine (or Gulo gulo) is native to the tundras and taigas of Northern Eurasia and North America. It has a stocky build with sturdy legs, a curved back, bear-like face, and small, rounded ears. It has thick brown-black fur with a yellow-white streak that runs from the head down each side of the body, rejoining at the tail. Wolverines grow between 65cm to 113cm long, 36cm to 45cm tall at the shoulder, and weigh between 9kg and 30kg. Males are slightly larger and significantly heavier than females.

Living in the tropical rainforests and grasslands of India, Bangladesh, Sri Lanka, Bhutan and Nepal, the sloth bear (or Melursus ursinus) is a medium-sized bear. It has shaggy, black fur, a light grey muzzle, and a distinctive grey-white crescent marking across its upper chest. The head is broad, with an oblong snout and hairy, tufted ears. Males and females look alike, but males are 10% to 20% larger than females, measuring between 1.4m and 1.9m long, 60cm to 90cm tall at the shoulder, and weighing 80kg to 145kg.

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.
