Widespread and abundant species evaluated as being at the lowest risk of extinction.

Aardvark
Orycteropus afer
The aardvark looks like an animal assembled from spare parts — rabbit ears, a pig's snout, a kangaroo's tail — and it is related to none of them, nor to the anteaters and pangolins it so closely resembles. It is the only living member of an entire order, Tubulidentata, named for its strange teeth: they have no enamel, are built from bundles of upright dentine tubes, grow continuously to replace what wears away, and sit only at the back of the jaw. It is a phenomenal digger, able to excavate faster than several people with shovels, and its burrows matter far beyond itself — warthogs, hyenas, porcupines, owls and hares all shelter in abandoned aardvark holes, making it a keystone species whose loss would evict an entire community. It hunts ants and termites by night, sweeping a long sticky tongue through nests it has torn open, and can seal its nostrils to keep the insects out. One plant depends on it entirely: the aardvark cucumber fruits underground, and the aardvark digs it up for its water and buries the seeds in its dung. Its likeness to other ant-eating mammals is convergent evolution — the same diet, solved the same way, by animals that are not related at all.

Aardwolf
Proteles cristata
The aardwolf is a hyena that gave up being a hyena. It looks like a small striped hyena and it is one, but where its relatives evolved bone-crushing jaws, the aardwolf abandoned the entire carnivore project and went after termites. It eats almost nothing else — as many as a quarter of a million in a single night, lapped up with a broad, sticky tongue — and it does not dig into their mounds but takes them from the surface as they forage. It specialises on one genus, Trinervitermes, which defends itself with a noxious terpene secretion that deters almost every other predator, and the aardwolf simply tolerates it. Its jaws have collapsed accordingly: the cheek teeth are reduced to widely spaced, useless pegs, and only the canines remain, kept for fighting rather than eating. It is nocturnal, largely solitary but monogamous, and it defends a territory containing enough termite mounds to see it through the year, marking the boundary meticulously.

Abyssal Comb Jelly
Bathocyroe fosteri
The Abyssal Comb Jelly, Bathocyroe fosteri, is a translucent, deep-sea ctenophore notable for its delicate, balloon-like body and shimmering rows of cilia used for locomotion. Found at great oceanic depths, this invertebrate often drifts in the midwater column, capturing small prey with its lobes. Its bioluminescent capabilities create mesmerizing light displays, which may serve as camouflage or to deter predators. Despite its fragile appearance, the Abyssal Comb Jelly is well-adapted to the extreme pressure and darkness of the deep sea.

Acorn Worm
Saccoglossus kowalevskii
Acorn worms are soft-bodied, burrowing marine invertebrates belonging to the class Enteropneusta. They are named for the acorn-like appearance of their proboscis, which is used for digging and feeding. Acorn worms play an important role in marine ecosystems by aerating sediments and recycling nutrients. These animals are considered evolutionary significant as they share characteristics with both vertebrates and invertebrates, offering insight into early deuterostome evolution.

Afghan Hound
Canis lupus familiaris
The Afghan Hound is an ancient breed of sighthound renowned for its elegant appearance, long silky coat, and distinctive ring curl at the end of its tail. Originally bred in the mountainous regions of Afghanistan, this dog was valued for its speed, agility, and ability to hunt game over rugged terrain. Afghan Hounds are known for their independent and sometimes aloof temperament, yet they are affectionate with their families. Their unique appearance and dignified demeanor have made them popular in dog shows and as companion animals worldwide.

African Barbet
Lybiidae
Barbets are plump, colorful birds found throughout tropical regions of Africa and Asia, known for their stout bills and bristle-fringed faces. Members of the family Lybiidae, African barbets are particularly noted for their bright plumage, which often includes striking reds, yellows, and greens. They primarily inhabit forests and woodland environments, where they excavate nest holes in trees. Barbets are vocal birds, producing distinctive, repetitive calls that can be heard over long distances. Their diet consists mainly of fruit, but they will also eat insects and other small animals.

African Bullfrog
Pyxicephalus adspersus
The African bullfrog inverts the usual amphibian rule that females are the larger sex: males can exceed 2 kg and grow roughly twice the size of the females they mate with, because male-male combat over breeding pools rewards bulk. Along the lower jaw sit three odontoid projections — bony, tooth-like spikes that let it hold struggling prey, and give a bite that draws blood. It eats essentially anything it can cram down, including rodents, birds, other frogs, and famously young cobras. Its most remarkable behaviour is paternal: a male guards the tadpole mass, and when the puddle begins to evaporate he will excavate a channel with his hind legs to drain water from a shrinking pool into a larger one, saving the shoal. He is not sentimental about it — he also eats a share of the tadpoles he is guarding. Between rains the frog burrows down and encases itself in a cocoon built from layers of shed skin, sealing in moisture, and can wait out drought underground for a year or more.

African Butterflyfish
Pantodon buchholzi
The African Butterflyfish is a distinctive freshwater fish known for its broad, wing-like pectoral fins and surface-dwelling lifestyle. Native to slow-moving rivers and swamps of West and Central Africa, this fish is specially adapted for life at the water's surface, where it hunts insects and small invertebrates. Its flattened body and upturned mouth allow it to capture prey efficiently, while its camouflage helps avoid predators. African Butterflyfish are popular in the aquarium trade due to their unique appearance and fascinating behaviors.

African cichlid
Various (notably Pseudotropheus zebra, Haplochromis burtoni, and others)
African cichlids are a diverse group of freshwater fish native primarily to the Great Rift Valley lakes of East Africa, especially Lakes Malawi, Tanganyika, and Victoria. They are renowned for their vivid coloration, complex social behaviors, and remarkable adaptability, with hundreds of species exhibiting a wide range of shapes and sizes. African cichlids are popular in the aquarium trade due to their striking appearance and active personalities, but they require specialized care. Their rapid speciation and ecological diversity make them a key subject in evolutionary biology studies. These fish play important roles in their native ecosystems, contributing to the unique biodiversity of African freshwater habitats.

African Civet
Civettictis civetta
The African civet is a nocturnal, medium-sized mammal known for its distinctive black and white markings and a mane of long hair along its back. It is famous for the musky secretion called civetone, which is used in the perfume industry. The species is solitary and highly territorial, using scent marking to communicate with others. African civets are agile climbers and swimmers, inhabiting a wide range of environments across sub-Saharan Africa.

African Clawed Frog
Xenopus laevis
Xenopus laevis is a frog built for a life entirely in water: it has no tongue, no eardrum and no visible ears, and it shovels food into its mouth with its hands. Along its flanks run rows of stitch-like sensory organs — a lateral line retained into adulthood, which is unusual for a frog and lets it feel the water displaced by prey in muddy ponds. Its "claws" are three black keratinised toe tips on each hind foot, used to shred carrion. Males call underwater without moving air at all, clicking by snapping cartilage discs in the larynx. Its strangest cultural role came in the 1930s, when the Hogben test made it the world's pregnancy test: hormone in a woman's urine, injected into a female frog, made her lay eggs within hours, and hospitals kept tanks of them for three decades. That global trade in laboratory frogs is now strongly implicated in spreading the chytrid fungus that has since devastated amphibians on several continents — Xenopus carries it while largely resisting it.

African Fat-tailed Gecko
Hemitheconyx caudicinctus
The African Fat-tailed Gecko is a medium-sized, nocturnal lizard native to West Africa. Recognized for its distinctive broad tail, which stores fat as an energy reserve, this gecko displays earthy color patterns with bold stripes or bands. It prefers arid to semi-arid environments, often sheltering under rocks or in burrows to avoid the harshest heat. Calm and docile, the African Fat-tailed Gecko is a popular choice for reptile enthusiasts due to its manageable size and hardy nature.

African Helmeted Turtle
Pelomedusa subrufa
The African Helmeted Turtle is a small to medium-sized freshwater turtle known for its distinctive domed shell and broad, flattened head. Found throughout much of sub-Saharan Africa and parts of the Middle East, it is highly adaptable and inhabits a variety of freshwater bodies, including ponds, lakes, and slow-moving rivers. This turtle is famous for its ability to survive in temporary water sources by burrowing into mud during dry periods, a behavior known as aestivation. It is an opportunistic feeder, consuming a wide range of animal and plant matter. African Helmeted Turtles are also known for their social basking behavior and occasional group hunting.

African Jacana
Actophilornis africanus
The African jacana runs the standard bird family upside down. Females are about 1.5 times heavier than males, hold a territory, and mate with up to four of them; the males build the nests, incubate the eggs, and raise the chicks alone. A father moves his brood by scooping the chicks up under his wings and walking off with four sets of tiny legs dangling from his flanks — one of the strangest silhouettes in African wetlands. The bird's most obvious feature is its feet: toes and claws so absurdly elongated that its weight is spread across floating lily pads, letting it stroll over open water and earning it the names lily-trotter and Jesus bird. Chicks can dive and hide beneath the surface, clamping onto submerged vegetation with only the bill tip exposed to breathe. It feeds on insects and snails picked from the undersides and surfaces of floating leaves, flipping pads over with the bill. Its range spans sub-Saharan floodplains, swamps and lagoons wherever water lilies persist.

African lungfish
Protopterus annectens
An African lungfish will drown if you hold it underwater. Its gills are vestigial and it must surface to fill a pair of true lungs — an obligate air-breather among fish. When its swamp dries, it burrows into the mud, secretes a mucus cocoon that hardens around it leaving a breathing tube to the surface, converts its ammonia waste into far less toxic urea, and drops its metabolism as much as sixtyfold. In that state it can wait out drought for months, and there are records of individuals reviving after several years. Its heart has a partly divided atrium and a spiral valve in the outflow tract, keeping oxygenated and deoxygenated blood partly separate — an arrangement much closer to an amphibian's than to a typical fish's. The thin, filamentous pelvic fins are not decorative: laboratory work has shown Protopterus lifting its body off the bottom and "walking" on them with alternating strides, which reframes how tetrapod-style locomotion could have begun in water rather than on land. Lungfish are lobe-finned, and are more closely related to you than to a salmon.

African Reed Frog
Hyperolius viridiflavus
The African Reed Frog is a small, agile amphibian known for its vibrant coloration and remarkable adaptability. These frogs are typically found in wetlands, marshes, and reed beds throughout sub-Saharan Africa, often displaying a variety of colors and patterns, ranging from greens and yellows to browns and even blues. Their skin secretes a waxy substance that helps prevent dehydration, enabling them to thrive in both permanent and temporary water bodies. African Reed Frogs are especially famous for their loud, distinctive calls during the breeding season, which can be heard echoing across wetlands at dusk and night.

African Rock Python
Python sebae
The African Rock Python is Africa's largest snake and one of the largest python species in the world. Characterized by its thick, muscular body and distinctive dark blotched pattern, it can grow up to 6 meters (20 feet) in length. This non-venomous constrictor is highly adaptable and found across a wide range of habitats, including savannas, forests, and near water bodies. African Rock Pythons are solitary and ambush predators, relying on stealth and power to subdue large prey such as antelope, monitor lizards, and even crocodiles. Despite their formidable size, they face threats from habitat loss and hunting.

Airedale Terrier
Canis lupus familiaris
The Airedale Terrier is the largest of all terrier breeds, known for its intelligence, versatility, and distinctive wiry coat. Originally bred in the Aire Valley of Yorkshire, England, this breed was designed to catch otters and rats between the Aire and Wharfe Rivers. Airedales have a dignified but lively temperament, making them excellent working dogs and family companions. They are highly trainable, energetic, and excel in various canine sports and working roles, including police and military service.

Akita Dog
Canis lupus familiaris
The Akita is a large and powerful dog breed originally from the mountainous regions of northern Japan. Renowned for their strength, courage, and unwavering loyalty, Akitas were historically used for guarding nobility and hunting large game such as bears and boars. They have a thick double coat, erect ears, and a curled tail, giving them a striking wolf-like appearance. Akitas are known for being reserved and dignified with strangers but affectionate and protective with their families. Their independent and intelligent nature requires consistent training and socialization.

Akita Inu
Canis lupus familiaris
The Akita Inu is a large, powerful dog breed originating from the mountainous regions of northern Japan. Renowned for its loyal and dignified temperament, the Akita Inu was historically bred for hunting large game such as bears, boar, and deer. With a thick double coat, erect ears, and curled tail, the breed is well-adapted to cold climates and harsh conditions. Akitas are intelligent and independent, requiring early socialization and consistent training, and are known for their reserved but deeply loyal nature towards their families.

Alaskan Malamute
Canis lupus familiaris
The Alaskan Malamute is a large, powerful breed of domestic dog originally bred for its strength and endurance to haul heavy freight as a sled dog in the Arctic. With a thick double coat, erect ears, and distinctive facial markings, Malamutes are well-adapted to cold, harsh environments. They are known for their friendly disposition, intelligence, and loyalty, making them beloved companions as well as working dogs. While they resemble wolves in appearance, they are a distinct, domesticated breed with a gentle temperament. Their high energy and need for exercise make them best suited to active families and experienced owners.

Alligator gar
Atractosteus spatula
The alligator gar is the largest fish that lives its whole life in fresh water in North America, reaching 2.5 m and over 130 kg, and it is armoured in a way no bony fish alive today matches. Its scales are ganoid: diamond-shaped, coated in a hard enamel-like layer of ganoine over a tough bony base, and interlocked into a lattice that behaves like chainmail — Native peoples used gar scales as arrowheads and gar hide as a covering for ploughs and shields. It breathes air through a vascularised swim bladder, which lets it hold on in the hot, oxygen-starved backwaters and oxbows where most predators suffocate. For most of the twentieth century it was branded a "trash fish" and deliberately culled by state agencies, which shot and netted them to protect sport fisheries; that view has reversed, and it is now valued as a native apex predator with a genuine appetite for invasive carp. It is also slow to recover from any of this: females may not spawn until around age ten and can live past fifty.

Alpaca
Vicugna pacos
The alpaca is a domesticated species of South American camelid renowned for its soft and luxurious fleece, which is prized in the textile industry. Smaller than its close relative, the llama, alpacas are gentle, social animals that thrive in herds and are primarily kept for their wool. Originating from the high Andes mountains, they are well-adapted to cold, harsh environments at high altitudes. Alpacas have a calm temperament and communicate through body language and a variety of vocalizations. Their unique appearance, marked by long necks and large, expressive eyes, makes them a favorite among animal enthusiasts.

Alpine Newt
Ichthyosaura alpestris
The Alpine Newt is a striking amphibian native to central and southern Europe, particularly thriving in mountainous regions. It is recognized for its slender body, smooth skin, and vibrant breeding colors, with males displaying a bright orange belly and blue flanks during the mating season. Alpine Newts are semi-aquatic, spending part of their lives in freshwater ponds and part on land in moist, shaded habitats. They are known for their adaptability, often inhabiting high-altitude lakes, forest pools, and garden ponds. Despite facing localized threats, their populations remain stable across much of their range.
