Why the Okavango River Never Reaches the Sea: Endorheic Basins Explained

The waters of the Okavango Delta do not flow into any ocean or sea. The river ends its journey by evaporating. It also seeps into the sands of the Kalahari Desert in Botswana. This is known as an endorheic river. The antonym is exorheic. This simply means it flows into a sea or an ocean.

On this editorial illustration of mine, I thought a sitatunga, an unique antelope species, would represent perfectly this beautiful ecosystem. It lives in the lush wetlands of Botswana. You can find it especially in the Okavango Delta. It is perfectly adapted to its aquatic habitat. It has elongated, splayed hooves. These allow it to move effortlessly through water. Its brown and white striped coat provides excellent camouflage. It hides well in the vegetation.

This contrastful wildlife illustration is great for nature magazine articles. You can also license it in educational infographics about African ecosystems. It would also make a beautiful book cover for wildlife guides or environmental presentations. The striking style even works well for the design of an ecology-themed board game
