The scimitar horned oryx is a small type of deer, but with huge horns. sadly, they are extinct now.

"The Sahel is a narrow band of semi-arid land that forms a transition zone between the Sahara to the north and the savannas to the south. It is made up of flat, barren plains that stretch roughly 5,400 kilometers (3,300 miles) across Africa, from Senegal to Sudan"

The red fronted gazelle is a widely unevenly spread animal, and it is on watch for extinction, but not too much. it is also a type of gazelle with (as it name says) has a red front

The dama gazelle lives in the sahara desert and the sahel, and it is almost extinct because of how overhunted it is. it is weird how it lives in the desert but feeds on grass.

The sahel is like a mix of the rainforest and the sahara desert. so like a temperate climate

The sahel mostly just has different animals and few minerals to come by
