Ruminant artiodactyls are a type of mammal with a special digestive system that allows them to chew food first, mix it with saliva, store it in the stomach for fermentation, and then swallow it again for re-digestion. Common ruminant artiodactyls include:
1. Cattle: Cattle are one of the most famous and widely distributed ruminant cloven-hoofed animals and one of the main agricultural livestock for humans.
2. Sheep: Sheep are also one of the main agricultural livestock and are often used to provide wool, meat and dairy products.
3. Deer: Deer are wild ruminant cloven-hoofed animals that are distributed around the world, especially in the forests and grassland areas of the Northern Hemisphere.
4. Horse: Horse is another widely distributed ruminant cloven-hoofed animal that is used for transportation, farming, sports competitions, and leisure activities.
5. Reindeer: Reindeer are ruminant cloven-hoofed animals that are only found in areas near the Arctic Circle. They are used by local residents to provide meat, hair, leather, and transportation.
6. Antelope: Antelope is a swift, cud-chewing, cloven-hoofed animal that is widely distributed in arid areas of Africa and Asia.
In short, ruminant artiodactyls are a very important group of mammals. They not only provide food and other commodities needed by humans, but also have important ecological and cultural values.
