Dire Horse

Common Name: Direhorse

Na'vi Name: Pa'li

Taxonomy: Equidirus hoplites or “feared armored horse”

Habitat: Rainforests and grasslands, but adaptable to most Pandoran environments. A grazing  animal that has been domesticated by the Na’vi as a riding animal.

Anatomy: Horse-like creature with six legs, tough skin with no fur, long necks and small head, bold stripes, flexible carbon fiber armor over shoulders and along the back of the neck and head.

Feeding Ecology: Land omnivore that uses long snout to feed on sap. some protein intake through insects trapped in sap. Favored food is direhorse pitcher plant. Effective pollinator.

Size: Over 4.25 meters long, up to four meters in height

Notes: Animal has neural interface that allows Na'vi and direhorse to move together with apparent effortlessness. A highly intelligent, calm creature that, like the Na'vi, can turn fierce in the face of battle.

Anatomy

The Direhorse is a large hexepodal (six limbed) grazing herbivore that shares characteristics of both Terran equine and ruminant animals. They eat vegetation almost exclusively, and possess a complex system of three stomachs, each specializing in the break down of specific types of biomass. Their six legs each end in a powerfully built hoof reinforced with a natural fiber weave much like the animal's skeleton. The reinforcement nearly eliminates the chances of a hoof cracking and splitting.

To fuel the muscles of their six powerful legs, the direhorse's lungs are fed directly by two rows of breathing valves located on the front of the chest, eliminating the rebreathing of air present in a windpipe when routed through the throat and mouth. The multiple valves also drastically increase the volume of air available, giving the animal impressive speed and endurance. The only drawback of this system is a direhorse cannot traverse water any deeper than its legs, as it will drown.

The direhorse has two prehensile neural interfaces that emerge from either side of the animal's skull. These appendages have feathery tips loaded with neurons and remain in constant motion as the animal explores its surroundings. In addition to their function as a link between herd members and their Na'vi riders, the interfaces also seem to possess a sensory function, much like the antennae of Terran insects. Xenobiologists believe that the touch of interfaces is for pleasure and affection, but also a means of transferring information about food sources and potential dangers; herds often move in unison shortly after touching antennae.

The animals are easily startled and can reach ninety-five kilometers per hour. The direhorse is larger by a third than the largest Terran draft horses such as the Clydesdale or the Percheron, and substantially larger than the biggest horse ever recorded on Earth. The Na'vi are excellent riders and the direhorse is a swift, nimble mount that is well-adapted to the rugged Pandoran terrain.

The Direhorse is a land herbivore found throughout most of Pandora's different environs. It is believed that it originated from the grassland regions, where herds of a few dozen to a few hundred animals range over territories of five hundred square kilometers or more. The direhorse's introduction to the planet's tropical regions probably coincided with its domesticated by the Na'vi.

On the plains, an adult direhorse had few natural predators that would risk challenging a herd. However in the jungle, the Thanator and Great Leonopteryx have both been observed isolating lost individuals and bringing them down with relative ease. Even a pack of Viperwolves have a fair chance to predate an adult direhorse cut off from the rest of the herd.

It grazes using its long snout and dexterous giraffe-like tongue, to feed on a wide variety of Pandoran flora, including grasses, ferns, and low lying leaves. In rain-forest environments, direhorses seek out beds of flowers for a quick caloric boost of sweet nectar, making the direhorse an important pollinator.

Many direhorses are tamed to aid their riders in the hunt and in battle. To bond with (or, in human terms, to “break”) a direhorse, a Na'vi must mount the animal and connect their neural queue to the animal's antennae (or neural whip). Once queue and antenna touch, the feathery tendrils automatically intertwine, almost as if possessed of free will. Although the exact motive force remains unknown, it is believed that the antennae may secrete a pheromone that evokes the unique intertwining.

Once intertwined, the Na'vi rider can communicate motor commands instantly through the neural interface. The apparent lack of effort makes it seem as if the direhorse is an extension of the rider's own body. This frees up the Na'vi to use a bow and arrow during a hunt or battle.

Unlike the Mountain Banshee, however, the neural link made between rider and direhorse does not lead to a life-long, exclusive bond between Na'vi and animal; although Na'vi have their favorite mounts, it is possible and permissible to ride another clan member's direhorse. The direhorse is a perfect mount to ride in the obstacle-strewn close quarters of a Pandoran forest; direhorses have excellent reaction times and can leap large distances.

Direhorses are the perfect war-fareing mount for the Na'vi, and played a crucial part in the showdown between Na'vis and humans. Direhorses are an important part of many Clans, such as the Horse Clan of the Plains (known as the Omatipa'li).

Na'vi Rituals

Mating

The Na'vi are monogamous creatures who mate for life. The mechanics of reproduction are similar to that of humans and other Terran mammals. However, their unique physiology provides the Na'vi with a level of intimacy unknown on Earth. Cultural anthropologists believe that when an appropriate mate has been selected (which can take many years), the male and female Na'vi will connect queues (called Tsahaylu) to create an emotional bond that lasts a lifetime. The intertwining of queues is both highly erotic and profoundly spiritual, but does not in itself lead to reproduction.[1]

Traditionally, once a Na'vi male has passed the tests on the path to manhood and has been accepted into the clan as an adult, he is not only allowed to make his bow from the wood of the Hometree, but he is also expected to choose his woman. After the woman has been chosen, the new couple are mated before Eywa.

Jake Sully chooses Neytiri to become his mate, and she accepts and mates with him under the Tree of Voices following his acceptance into the Omaticaya clan as 'One of the People'.

Once Tsahaylu is made between the couple, the ultimate in intimacy, pleasure that is unfathomable to humans, causes the somewhat unwillful sharing of the couple's good memories, and is a sign of Eywa's acceptance. If a couple can be foreseen to not have a pleasant or happy future, Eywa has been known to reverse the feeling produced by making Tsahaylu, a sign to the couple that mating would only, in simple words, ruin their lives together, and therefore prevents the mating, because of it's life-long span. After the resulting embracing and kissing, the couple is sent to sleep by Eywa, and the two dream hintings of their future together. The couple will experience the pleasure of Tsahaylu from the moment of connection, until they awaken and have completed mating, when they disconnect and return to the clan, mated for life.
