The dark unicorn, is interestingly one of the rarest Unicorns on Earth. Unfortunately it is on the endangered list of magical animals with only five recorded Dark Unicorns left.

Curiously a Dark Unicorn is pitch black including its mane, in addition its eyes are blood red the same as its horn. The young of dark unicorns weirdly are born hairless but with pitch black  skin and blood red eyes and horn, they do not grow hair until they are 300 years old.

All dark Unicorns live in deep dark caves in high mountains where no human has explored. They prey on Sun and golden Unicorns and water Pegasus who migrate to the high mountains to give birth.
