Coje Ya Menia is a water lion of Central Africa (Upper Cuango and Cuanza Rivers, Angola, and smaller tributaries). Slightly smaller than a hippopotamus. Has tusks or large canine teeth. Nocturnal. Amphibious. Moves to smaller rivers and swamps during the rainy season. Makes a loud, rumbling roar. Kills hippopotamuses but does not eat them. Tracks are like an elephant’s but with toes overprinted on the impression of the sole.
In the 1930s, a Portuguese truck driver heard that a Coje ya menia had killed a hippopotamus along the Cuango River the night before. He went off with some trackers and for several hours followed the trail of the hippo and another smaller animal. They found the dead, uneaten hippo ripped to shreds in an area where the grass and shrubs had been crushed down.
