1. Camel
A camel is an even-toed ungulate belonging to the genus Camelus, known for the distinctive fatty humps on its back. These humps store energy in the form of fat, which camels can metabolize when food and water are scarce. Camels are native to arid regions of Asia and Africa and have been domesticated for thousands of years for transportation and milk.

3. Cows
Cattle (Bos taurus) are large, domesticated, cloven-hooved herbivores. They are a prominent member of the subfamily Bovinae and the most widespread species of the genus Bos. Adult females are referred to as cows, while adult males are called bulls.
Cattle are commonly raised as livestock for meat (beef or veal, see beef cattle), for milk (see dairy cattle), and for hides, which are used to produce leather. They are also used as riding animals and draft animals (oxen or bullocks), pulling carts, plows, and other implements. Another product of cattle is dung, which can be used to create manure or fuel. In some regions, such as parts of India, cattle hold significant religious importance. Some small breeds, such as the Miniature Zebu, are even kept as pets.
Different types of cattle are associated with different geographic regions. Taurine cattle are found primarily in Europe, temperate parts of Asia, the Americas, and Australia. Zebus (also called indicine cattle) are common in India and tropical areas of Asia, the Americas, and Australia. Sanga cattle are native to sub-Saharan Africa. These types, which are sometimes classified as distinct subspecies or species, are further divided into over 1,000 recognized breeds.
Taurine cattle were domesticated around 10,500 years ago from a small population of wild aurochs in regions including central Anatolia, the Levant, and Western Iran. A separate domestication event occurred in the Indian subcontinent, giving rise to zebu.
As of 2025, the global cattle population is estimated to be approximately 1.6 billion, according to the most recent data from the Food and Agriculture Organization (FAO). Cattle are the largest single contributor of greenhouse gases from the livestock sector and are responsible for an estimated 10% of global greenhouse gas emissions. In 2009, cattle became one of the first livestock species to have a fully mapped genome.
4. Dog
The dog, or domestic dog (Canis familiaris or Canis lupus familiaris), is a domesticated descendant of the wolf and is characterized by an upturned tail. Derived from an ancient, extinct wolf species, the modern wolf is its closest living relative. Dogs were the first species to be domesticated by humans, more than 15,000 years ago, before the advent of agriculture.
The dog has been selectively bred for a wide range of behaviors, sensory capabilities, and physical characteristics. Breeds vary greatly in size, shape, and color. Dogs serve many roles for humans, including hunting, herding, protection, assisting police and military, providing companionship and therapy, and helping people with disabilities.
They are found worldwide and, as of 2022, are among the most popular domestic pets. There are more than 350 recognized dog breeds.
5. Pigeon
Pigeons and doves are members of the bird family Columbidae, which includes about 310 species. These birds are characterized by stout bodies, short necks, and slender bills. They primarily feed on seeds, fruits, and plant material.
