The ostrich horse is a domesticated animal used frequently in the Earth Kingdom, Fire Nation, and the United Republic of Nations as a mount or beast of burden
Ostrich horses are bipedal creatures exhibiting both ratite and equine characteristics. They exhibit morphological traits including elongated and robust hind limbs typically characteristic of a cursorial lifestyle.
They also bear a modified anisodactyl toe arrangement, with a hallux facing backward and two functional digits facing forward, all of which have claws. These powerful hind limbs allow ostrich horses to maintain high speeds over long distances, jump considerable heights, and run short distances along vertical surfaces.
The ostrich horse has a robust body and possesses short elliptical wings, accounting for its flightlessness. It has an elongated head with a broad yellow beak that is strongly decurved, two ears located posterior to the orbit, and a thick neck.
Ostrich horses are covered almost entirely with coarse brown feathers. The only exceptions are the head region covered by coarse tan hair and the caudal region, which can consist of either white or brown hair. The head can also be covered with a mane appearing either white or tan in coloration. Short manes extend from behind the ears to the middle of the neck, whereas long manes extend from behind the ears to the shoulders. The wing tips also vary among individuals, as they can appear either brown, tan, or white in coloration.
The ostrich horse exhibits characteristics from both of its namesakes. Although the ostrich horse retains the general avian body structure, it exhibits traits seen in horses, including an odd number of functional digits, a third trochanter on the femur, and hair as the primary body covering. Ostrich horses bear resemblance to many ratites, which includes the order to which ostriches belong. The equine characteristics which it exhibits can also be attributed to many members of the Equidae family, which includes horses, donkeys, and zebras.
