This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Ciguapa (Dominican Republic)
A Ciguapa is a mythological creature of Dominican folklore. They are commonly described as having human female form with brown or dark blue skin, backward facing feet, and very long manes of smooth, glossy hair that covers their bodies. They supposedly inhabit the high mountains of the Dominican Republic.
These creatures have nocturnal habits. Also, due to the position of their feet, one can never quite tell which direction the beings are moving by looking at their footprints. Some people believe that they bring death, and it is said that one should not look them in the eye, otherwise the person is at risk of being bewitched permanently. The only vocalization made by ciguapas is said to be a kind of whine or chirping.
