Grootslang

The Grootslang is from the Dahomey people of West Africa. They are thought to be the size of elephants with snake tails. They live in caves and swamps on the west coast. There have been some sightings of a creature resembling a Grootslang. These creatures are large and dark, but whether or not they are thought to have legs is not consistent. Many sightings of Grootslangs come from the Orange River. The earliest recorded sighting is from 1867 by Hans Sauer who saw a large dark snake in the Orange River. Sightings of the creature are almost always just large serpents without any elephant features.
