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; Direhorse can turn on a dime, have excellent reaction times, and can leap large distances.
When wild, the animals move together in a loose herd through the forests, feeding on tree bark and shrubs. Herds numbering in the dozens have been spotted from aircraft. But evidence (including scatological and plant impact) suggests that herds of more than one hundred animals are not uncommon.
The animals are easily startled, and, when all six legs are working in unison, 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.
