Alpacas are fluffy, gentle mammals from the camel family. They are closely related to llamas, but they are usually smaller and are best known for their soft, warm fleece.

A bull is an adult male domestic bovine that has not been castrated. Bulls belong to the same species as cows and can come from dairy or beef breeds in many colours, sizes, and horn shapes. They are powerful ruminants with muscular necks and shoulders, broad fields of vision, complex stomachs for digesting plants, and behaviour that should always be respected from a safe distance.

Camels are desert-ready mammals famous for their humps, long eyelashes, wide feet, and amazing ability to survive in dry places. They have helped people travel, carry goods, and live in harsh desert regions for thousands of years.

Chickens are domesticated birds raised around the world for eggs, meat, and feathers. They have short wings, heavy bodies, combs, wattles, beaks, claws, and many funny behaviors such as scratching, dust bathing, and clucking.

Cows are gentle farm animals that belong to the cattle family. They are large hoofed mammals that eat plants, live in herds, make milk, and have helped people for thousands of years.

Donkeys are sturdy mammals in the horse family. They are known for long ears, strong bodies, careful steps, loud brays, and their long history of helping people carry loads and travel in tough places.

Goats are curious, clever mammals in the same animal family as sheep. They are known for climbing, nibbling plants, living in herds, making milk, and sometimes having horns and beards.

Geese are large waterbirds related to ducks and swans. They are known for loud honks, long necks, webbed feet, strong flying, family groups, and traveling in flocks across lakes, fields, wetlands, and skies.

A hen is an adult female chicken. Domestic chickens are commonly classified as Gallus gallus domesticus, the domesticated form of the Red Junglefowl, with some ancestry from other junglefowl populations. Young females are called pullets before reaching maturity. Hens are social, ground-feeding birds with excellent color vision, strong feet for scratching, a muscular gizzard for grinding food, and complex calls and body language. Depending on breed, age, season, health, and daylight, a hen may lay many eggs with or without a rooster present.

Hog is a common word for a domestic pig and is also used for feral pigs or wild hogs. This page focuses on the domestic pig, which the Mammal Diversity Database recognizes as Sus domesticus, while many other authorities write Sus scrofa domesticus because domestic pigs descend from Eurasian Wild Boar. Hogs are intelligent, social, even-toed mammals with flexible snouts, strong senses of smell, continuously growing canine tusks, and omnivorous diets. Escaped domestic pigs and wild-boar hybrids can form damaging feral populations outside their native range.

Horses are strong, graceful mammals that have helped people travel, farm, play sports, and carry loads for thousands of years. They are known for fast running, flowing manes, powerful legs, and close bonds with humans.

A lamb is a young domestic sheep, Ovis aries, usually during its first year of life. An adult female is a ewe and an adult male is a ram. Lambs may be born with woolly, hairy, white, black, brown, spotted, or mixed coats depending on breed. Soon after birth, a healthy lamb attempts to stand, find its mother's udder, and drink antibody-rich colostrum. It begins life as a milk drinker, then gradually develops the four-part digestive system needed to graze and ruminate like an adult sheep.

Llamas are tall, sturdy mammals from the camel family. They are closely related to alpacas and have been used for carrying goods in South America for thousands of years.

A mule is the hybrid offspring of a male donkey, called a jack, and a female horse, called a mare. Mules can inherit a horse-like body along with long ears, strong hooves, and other donkey traits. People have carefully raised them for thousands of years as riding, pack, farm, and transport animals.

An ox is a domestic bovine trained to pull loads and perform other work. Most oxen are adult male cattle that were castrated when young, but cattle of different sexes and breeds can be trained for draft work in some traditions. For thousands of years, these patient, powerful animals have helped people plough fields, move carts, haul timber, and power farm equipment.

A pony is a small type of domestic horse, not a baby horse. Many organizations use a mature height near 14.2 hands at the withers as the dividing line, although breed traditions and competition rules can differ. Ponies share the same species as other domestic horses, Equus caballus, and many have sturdy bodies, strong legs, thick manes, and hardy coats.

A ram is an adult intact male sheep, not a separate species. This page focuses on domestic sheep, Ovis aries. Rams vary enormously among breeds: some carry thick curling horns, some have smaller horns, and others are naturally hornless or polled. They are social grazing mammals with excellent side vision, multi-chambered stomachs, strong flock instincts, and powerful breeding-season behavior.

A rooster is an adult male domestic chicken, not a separate species. Domestic chickens are commonly classified as Gallus gallus domesticus and descend mainly from red junglefowl, with genetic contributions from other junglefowl. Roosters vary enormously among breeds, but many have a large comb, hanging wattles, curved tail feathers, pointed neck and saddle feathers, strong legs, and a ringing crow.

Sheep are gentle, woolly mammals that often live in flocks. People have raised sheep for thousands of years for wool, milk, meat, and help managing grassy land.

Turkeys are large birds with strong legs, rounded bodies, fan-shaped tails, bare heads, and funny-looking skin parts called wattles and snoods. Wild turkeys can fly short distances, while many farm turkeys are too heavy to fly well.

For thousands of years, people have raised water buffalo for milk, farm work, transport, meat, and manure. These huge bovids are especially at home in hot, wet landscapes where broad feet cross soft ground and a muddy wallow provides relief from heat and insects. Domestic water buffalo are different from both African buffalo and the rare wild water buffalo.

Yaks are shaggy hoofed mammals built for cold mountain life. They have long hair, strong bodies, curved horns, and tough hooves that help them live on high plateaus where the air is thin and winters are icy.
