Aardvark
A secretive nocturnal African mammal with a pig-like snout and long sticky tongue — the only living species in its entire order, an evolutionary singleton that has changed little in tens of millions of years.

Below are animals that contain the letter K anywhere in the name. Each of the 27 animals below opens to a full profile.
A secretive nocturnal African mammal with a pig-like snout and long sticky tongue — the only living species in its entire order, an evolutionary singleton that has changed little in tens of millions of years.
The striking leaf-eating monkey of African forest — the black-and-white colobus is one of Africa's most visually dramatic primates, with jet-black fur contrasting with white facial frame, a long white mantle over the shoulders, and a white-tipped tail; colobus monkeys eat mainly mature leaves that other primates avoid, relying on a specialised sacculated stomach to ferment and detoxify the leaf material.
The tiny antelope of African thornbush — one of the world's smallest antelopes, barely 35–45 cm at the shoulder, with enormous dark eyes, an elongated flexible snout, and a habit of zigzagging away in a characteristic stop-start dash when alarmed; dik-diks form lifelong monogamous pairs that maintain small territories together, marking boundaries with secretions from preorbital glands beside their eyes.
A patient, sure-footed working equid descended from the African wild ass — the world's primary cargo animal in mountainous and arid regions for over 5,000 years.
A large deer of North America and East Asia — second only to moose among living deer in size, with massive antlers grown anew every year by males.
The giraffe gazelle of East African thornbush — the gerenuk has an extraordinarily long neck and legs that allow it to stand bipedally on its hind legs to browse up to 2 metres high in acacia bushes; the only antelope that routinely stands on its hind legs to feed; a Somali name meaning giraffe-necked describes it precisely; unlike most antelopes, it never drinks water, obtaining all moisture from browse.
A medium-sized canid of Africa and Asia — a highly adaptable scavenger and hunter that forms monogamous lifetime pairs and cooperatively raises young, serving an essential ecological role as a cleanup crew.
The largest living marsupial and Australia's emblematic animal, a powerful hopper that can clear 9 m in a single leap and travel 70 km/h across arid plains.
A golden, nocturnal rainforest mammal related to raccoons — it has a prehensile tail for gripping branches, an extraordinarily long tongue for extracting flower nectar (making it an important pollinator), and large dark eyes adapted for night vision; it sleeps in hollow trees by day and is one of the few carnivores that has adopted a largely frugivorous and nectarivorous diet.
A slow, eucalyptus-eating Australian marsupial with thick fur and a specialized digestive system, often called a "bear" but unrelated to true bears.
The world's largest living lizard — a monitor lizard of the Indonesian islands that can reach 3 metres and 70 kg, kills large prey including deer and water buffalo with venom-laced saliva and a bacteria-laden bite, and can reproduce by parthenogenesis; its ancient lineage and isolated island habitat make it genuinely prehistoric in character.
The national animal of Pakistan — a large wild goat of the Himalayas and Hindu Kush with spectacular spiral horns that in old males can reach 160 cm; the horns spiral outward in a tight corkscrew, unique among wild goats; the markhor lives on vertiginous cliff faces inaccessible to most predators and is revered in the region — its Farsi name means "snake eater," though it does not actually eat snakes.
A small social mongoose of southern African deserts — famous for upright sentinel posture, tightly cooperative family groups, and starring roles in nature documentaries and "The Lion King."
A small, intelligent New World monkey famous for its tool use and dexterity, named after the brown-and-white robes of Capuchin friars and the most studied genus of monkey in cognitive research.
A massive Ice Age survivor of the Arctic tundra — famous for the defensive circle it forms against wolves, its extraordinarily warm qiviut wool, and the musky odour males produce during rut.
A secretive forest giraffe of the Congo Basin — the only living relative of the giraffe, despite looking more like a striped horse, and completely unknown to Western science until 1901.
A small, round-eared relative of rabbits that lives on rocky mountain slopes and alpine meadows — unlike its rabbit relatives, it does not hibernate but instead spends summer frantically collecting and drying grasses and wildflowers into hay piles for winter; its distinctive high-pitched call echoes across talus slopes.
The monkey with the most extraordinary nose in the animal kingdom — the male's enormous, pendulous nose can grow longer than 10 cm, acts as a resonating chamber to amplify calls, and appears to be a signal of genetic fitness to females; found only in the rainforests and mangroves of Borneo.
A small, herbivorous Australian marsupial nicknamed the "world's happiest animal" for its perpetually grinning face, found only on Rottnest Island and in small mainland populations.
An ancient cartilaginous fish that has roamed the oceans for over 400 million years — predating dinosaurs by hundreds of millions of years — with over 500 living species ranging from the 18 cm dwarf lanternshark to the 18 m whale shark.
A black-and-white mammal famous for its sulfurous defensive spray — capable of accurate spraying up to 3 meters, with a smell so persistent it can linger for days even after washing.
A legless reptile of nearly every habitat on Earth — over 3,800 species ranging from the 10 cm thread snake to the 6 m anaconda, with sophisticated venom systems and an extraordinary ability to swallow prey larger than their heads.
South Africa's national animal and emblem — a graceful medium-sized antelope of the Karoo and Kalahari known for its spectacular "pronking" display, in which it springs repeatedly into the air with arched back and stiff legs; once migrated in herds of millions across southern Africa.
The ungainly giant of Himalayan forest — the takin looks improbable, like a goat that has been assembled from spare parts; it has the massive body of a musk ox, the Roman nose of a wildebeest, a short tail, and a yellow-gold coat; it is the national animal of Bhutan, where it is closely associated with the Divine Madman's legend; one of the larger bovids of Asia and a herd animal of dense rhododendron and bamboo forest.
A kangaroo that climbs trees — tree kangaroos are macropods that returned to an arboreal life from terrestrial ancestors, re-evolving the short, curved claws, flexible forelimbs, and long counterbalancing tail needed for life in the forest canopy; they are slow and clumsy on the ground but agile in trees, able to leap between branches and drop 18 metres to the forest floor without injury.
A South American monkey with a strikingly bare red face — health visible at a glance — that lives in flooded Amazonian forests and is among the most threatened primates in the Americas.
A massive long-haired bovine of the high Himalayas, central to Tibetan and Mongolian life as a beast of burden, milk producer, and source of meat, fiber, and butter for tea.
