The term 'Zebra Cousins' refers to the two species of African wild ASSES, the Somali Wild Ass and the Nubian Wild Ass. Both species are members of the Equidae family, which includes horses, donkeys, and zebras. The Somali Wild Ass is native to the Horn of Africa, while the Nubian Wild Ass is native to the eastern part of the Sahara Desert. Both species are endangered due to habitat loss and hunting. They are closely related to zebras, and share many of the same physical characteristics, such as stripes and a long mane.
