The Namib is a coastal desert in southern Africa. The name Namib is of Khoekhoegowab origin and means "vast place". 

According to the broadest definition, the Namib stretches for more than 2,000 kilometres (1,200 mi) along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa. 

The Namib's northernmost portion, which extends 450 kilometres (280 mi) from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert. 

Living in the heart of the Kaokoland and Damaraland regions in the far north of Namibia, one will find herds of desert adapted Elephants that survive in the harsh climate of the desert with very little water.

Desert adapted Elephants are found in only two locations in the world; in Mali and in the northern reaches of Namibia. In Namibia one can find them along the dried up riverbeds of the Kaololand and Damaraland areas of Namibia.

Much debated has been had over whether these specially adapted Elephants should be classified as a completely different species or not, but for now they are considered the same species as an African Elephant but with adaptations.

While these Elephants are the same species as the Africa Elephant they can appear leaner and taller due to their diet and have bigger feet than other African Elephants. The larger size of their feet allows them to walk with more ease across the very soft desert sand, an adaptation that is useful when you consider that fact that these elephants have been known to travel up to 200 kilometres (124 miles) in search of water.

The other two main adaptions found in the Elephants is their use of water and their feeding patterns. Their smaller size also means that they need less water to survive. These Elephants also have slightly longer trunks to allow them to dig down into the sand in search of the water that might be running underground.
