The animals of the Sahel are the: the scimitar-horned oryx, dama gazelle, Dorcas gazelle, red-fronted gazelle, the giant prehistoric buffalo, The Bubal hartebeest, African wild dog, the Northwest African cheetah, the Northeast African cheetah, the West African lion, and the East African lion. (i will only do a few of them)
The scimitar horned oryx is a small type of deer, but with huge horns. sadly, they are extinct now.
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.
