This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Encantado (Brazilian)
The Encantado originate in early mythology of the area now comprising Brazil, Bolivia, and Paraguay, and are shapeshifting dolphin-men that roam the amazon river. The word “encantado” translates to “enchanted” in Spanish and Portuguese, and is normally used when introducing oneself. In this case of these mythological creatures, however, it translates to “the enchanted one”.
In human form they are pale-skinned and graceful, dressed usually in bright clothes in an old-fashioned style. Their transformation is never fully complete, however: an encantado will always have a bald spot on the top of its head where its dolphin blowhole remains. For this reason, the encantado always keeps his head covered, usually with a broad-brimmed straw hat. The encantado is better at assuming its dolphin form, though strange boto with flippers ending in human hands have been reported.
