Unknown Sirenian of Central Africa.

Variant name: Guidiara (in Guinea, “water 

Physical description: A large fish or octopus. 
Head is like a gorgon’s. Tentacles.

Behavior: Sucks blood and eats the brains of 
infants. Hides among rocks in the river and attacks 
passing canoes.

Distribution: Mbomou River, Central African 
Republic; Uele and Dungu Rivers, Democratic 
Republic of the Congo; Niger River, Guinea.

Possible explanations: 
(1) A F reshwater Octop us, though all 
known cephalopod species are exclusively 
marine, and none are sanguinivorous. 
(2) Evidence for an extended range of the 
West African manatee (Trichechus 
senegalensis), proposed by Bernard 
Heuvelmans. Adults are generally 9–10 feet 
long. This animal is found in rivers, 
estuaries, swamps, and lagoons from the 
Senegal River in the north to the Cuanza 
River, Angola, in the south, and it occurs as 
far as 1,200 miles from the sea along the 
Niger River. Its presence in certain 
tributaries of the Congo has been suspected 
but never confirmed. Its reputation as a 
brain-eater is probably fear-based, since all 
known sirenians are herbivorous. 
(3) A giant Catfish (Family Siluridae), 
suggested by Marc Micha.


The Migas, according to many  accounts, is believed to possess human-like features such as legs. However, the creature does not commonly leave the water, and finds its food source by sucking blood and brains out of infant human beings by hiding among rocks and striking out at passing canoes for an easy meal.
