Inkanyamba:

The Inkanyamba is a huge carnivorous eel-like animal, often found in legends of the Zulu and Xhosa people. Ancient legends say Inkanyamba’s can control the weather. These creatures are believed to have fins and grow to enormous sizes. While, there are actually freshwater eels in South Africa that grow to around six feet long, they are apparently found lacking compared to the stories of the Inkanyamba

Impundulu:

The Impundulu or Lightning Bird is no ordinary bird. Stories of this monstrous bird, which grows to the size of a human, can be found in Pondo, Zulu, and Xhosa folklore. This magnificent bird can apparently summon lightning and storms, hence the name. The bird is allegedly a shape shifter as well, that can appear as a human, and is sometimes a supernatural familiar that guards a witch or witch doctor. Due to its size and nature, it will attack people and drink their blood.
