According to "Entertainment Weekly", "The Na'vi can commune with animals on their planet by literally plugging their ponytails into the creatures' nerve systems. To become a warrior, a Na'vi must tame and ride a creature known as Ikran." The Na'vi also use this system to mate with a "life partner". They make a bond that cannot be broken in the Na'vi's lifetime.
