Sphinx

The Sphinx is a species of odd toed ungulate from the equine family. They are considered to be closely related to both Ponies and Griffons as they share traits with both those species.

They mostly live in Hetra.

Characteristics
They have six limbs, with a pair of feather-covered wings and four feline-like legs with 5 toes each.

Like Griffons, they have a long tail with hair at the end.

Evolution
The most commonly accepted theory is that, in their divergent evolution from Ponies, an ancestor of Sphinxes which probably lived in Buffalo Nation evolved paws as an adaptation to the sandy soil of the desert, which is less friendly to hooves.

According to this theory, the westernmost populations of such ancestor would become the Sphinxes, the easternmost ones would become the Griffons and the middle ones would become the manticores.
