Coje Ya Menia
The Coje Ya Menia is a cryptid from Angola. They are aquatic creatures fitting the cryptozoological classification of Water Lion. They are slightly smaller than a hippopotamus and have large canine teeth, or tusks. They are nocturnal and move around in smaller amounts of water during the rainy season, while typically living in rivers and swamps. They can be identified by their loud, rumbling roars and their elephant-like footprints. They are known to kill hippos but not eat them. It has been suggested that they are surviving saber tooth tigers, giant monitor lizards, or some form of surviving dinosaur.
