The Ninki Nanka is from West African folklore. It is said to have the head of a horse with three horns; two horns point out or backward and the third central horn points forward. It has the neck of a giraffe and the body of a crocodile.
According to legend, it mostly feeds on cocky children; it is extremely large and dangerous and when children disobey their parents and go into the swamp by themselves, they fall victim to the Ninki Nanka.
It is also seen as an omen of imminent death. Nearly everyone who has claimed to have seen it has died shortly afterward.
It is possible that the beast may have been inspired by dinosaur fossils—Africa has been a rich source of sauropod bones.
Mokèlé-mbèmbé means “one who stops the flow of rivers” in the Lingala language. This is a legendary water-dwelling creature of Congo River basin folklore and closely resembles the extinct sauropods of the dinosaurs’ reign. It is usually described as being gray-brown in color, and it prefers river bends and deep water in its jungle habitat. Some cultures, such as those of Boha Village, describe the creature as a spirit rather than a flesh-and-blood animal. Some reports describe it as being more like elephants, rhinoceroses, and other known large animals. Since neither species of African rhinoceros is common in the Congo Basin, the mysterious animal may be a combination of mythology and folk memory from a time when rhinoceros were actually found in the region.
Numerous expeditions to Africa in search of Mokèlé-mbèmbé have been launched, and some have reported close encounters. However,there have been sightings of it for the past two hundred years, but no one has photographed it or produced any physical evidence that it exists.
