Camels:
* Dromedary camels: These camels have one hump and are found in the Middle East and Africa.
* Bactrian camels: These camels have two humps and are found in Central Asia.
Other humped animals include:
* Guanacos: These South American camelids have a small, single hump.
* Vicuñas: These South American camelids also have a small, single hump.
* Alpacas: These South American camelids have a small, single hump, but it's not as prominent as in other camelids.
* Llamas: These South American camelids technically have a hump, but it's very small and often goes unnoticed.
* Zebu: This type of cattle has a distinctive hump over its shoulders.
Note: While some animals, like the bison, may appear to have a hump, it's actually just a build-up of muscle on their back.
Why do these animals have humps?
Humps serve different purposes depending on the animal:
* Camels: Their humps store fat, which provides energy when food is scarce.
* Guanacos, Vicuñas, Alpacas, and Llamas: Their humps are smaller and likely help with balance and agility in their mountainous environments.
* Zebu: Their hump helps them regulate their body temperature in hot climates.
Ultimately, the presence of a hump is an adaptation that helps these animals thrive in their specific environments.
