Imperial Unicorn

Imperial Unicorn, Equus monoceros is a species of horse native to most of Europa. It is seen on the coat of arms of the United Kingdom. However, it is very rare and most people consider it to be mythical.

Description
The Imperial Unicorn stands at 15 hands for stallions, while mares stand at 14.5 hands. They are mostly white in colour, but may also be black, cream, bay, chestnut or liver in colour.

Similar species
They closely resemble domestic breeds of horses, like the Quarter Horse, but they lack the unmistakeable horn.
