The Danube crested newt (or Triturus dobrogicus) is an amphibian species living in the slow-flowing waters, tributaries and surrounding woodlands of the Danube River. Sides and back of the newts are covered in black and brown skin with white and black mottling, while their belly and throat are coloured bright red and orange with dark patterns. As with all crested newts, the species expresses sexual dimorphism where males have a distinctive spiked crest running down the length of their spine during breeding season.

The Nile lechwe (or Kobus megaceros) is a species of ungulate native to the marshes and swamps of South Sudan and Ethiopia. They exhibit a high level of sexual dimorphism: male Nile lechwes are larger than females, with a length of 1.6m to 1.8m, shoulder height of 1m to 1.05m and weight of 90kg to 120kg. They have long ridged horns and their coat is of a dark brown colour, with white markings on the shoulders, face and legs. The male’s neck is covered with longer, bushy hairs. Conversely, female Nile lechwes do not have horns and have a much lighter tan coloured coat.

Among the largest of cranes, the red-crowned crane (or Grus japonensis) is a species of wading bird native to the wetlands, rivers and tidal flats of eastern Russia, China, Mongolia, Korea and Japan. Many cranes migrate and spend their summer in Russia, China and Mongolia, and the winter in Korea and China. Japan’s population of red-crowned cranes however are residents and do not migrate. The plumage of red-crowned cranes is white, with black tail feathers, neck and face, as well as a row of black feathers on the wings.

The wild water buffalo (or Bubalus arnee), also known as the Asian water buffalo, is a very large species of bovine living in the marshes, swamps and flood plains of central east and southeast Asia. Its present range is extremely fragmented, with the majority of animals living in India, and other populations surviving in Nepal, Bhutan, Thailand and Cambodia. Wild water buffaloes have grey to black skin, with coarse dark hair covering the body sparsely, and an elongated head with small ears.

The spectacled caiman (Caiman crocodilus) is a medium-sized crocodile that lives in the wetlands, savannahs and forests of Central and South America. It can be green, brown, yellow or gray, with bands on the tail and body. It gets its name from the distinctive bony ridge it has between its eyes which makes it appear as if it is wearing glasses. The body of this caiman is slender, with other ridges of scales on the back. The male measures between 1.50 and 2 m in length on average (although with age some reach 2.50 m) and weighs between 13 and 40 kg.

Native to the rivers and streams of Central and Southeast Asia, the Asian small-clawed otter (or Aonyx cinereus) is the smallest otter species in the world. Its sleek body is covered in brown fur, with a white belly and throat. Asian small-clawed otters grow between 72cm and 96cm in total body length and weigh 2.7kg to 5.4kg. There are no notable physical differences between females and males of this species.

The platypus (or Ornithorhynchus anatinus), also known as the duck-billed platypus, is a monotreme mammal native to streams, pools and rivers of Eastern Australia including the island of Tasmania. It has thick brown fur, wide webbed and clawed feet, a broad flat tail and a characteristic flat bill. Male platypus measure 42cm to 60cm in length, with a weight of 0.8kg to 2.5kg; whereas females are 38cm to 55cm long, weighing 0.65kg to 2kg.

The capybara (or Hydrochoerus hydrochaeris) is the world’s largest rodent and lives throughout savannahs, forests and wetlands of South America. Its large, barrel-like body is covered in coarse brown fur. Capybaras have partially webbed feet to accommodate their semiaquatic lifestyle, a short vestigial tail, and small ears on their oblong shaped head. They typically measure 50cm to 62cm in height and 106cm to 134cm in length. Although similar in size, female capybaras tend to be heavier than males, with an average weight of 61kg for females and 50kg for males.
