Mahamba is a lake cryptid purported to lurk in the Democratic Republic of the Congo, around the Lake Likouala swamp region.
Description
Mahamba is rumoured to be an enormous crocodile; reaching lengths of up to 50 ft. The Bobangi aboriginals have proclaimed this animal to be unlike any other they have seen, and have only compared it to other creatures, such as a Nkoli (the Bobangi word for crocodile) or the legendary Nguma-Monene for the sake of comparison.
Theory
Some have speculated that it is a freshwater relic of the Mosasaurus; a huge, sea-dwelling lizards which were presumed extinct by the end of the Cretaceous period.
