One of the rarest large predator in the protected area is the Northwest African cheetah (Acinonyx jubatus hecki). As of 2007, there were only about 5–13 individuals left in the national park and neighboring W National Park.[4] The West African lion (Panthera leo leo) population in the W-Arly-Pendjari Complex comprised about 100 animals[when?] and is possibly the largest in West Africa.[5]
