They are, however, much larger and typically stronger than humans. Na'vi are normally about 3 meters in height. This may be in part due to Pandora's lower gravity than Earth, which, after time will cause a person to "get soft" (as Colonel Quaritch put it). Their skeletons are reinforced with naturally occurring carbon fiber, making their bones extremely rigid and hard to bend-(but they easily crack under focused pressure). Their hands are graceful, with three very long fingers, and one opposable thumb. However, it should be noted that human-grown Na'vi (the [[Avatar]]s) have four main fingers in addition to the opposable thumb just as in the human hand. The faces have high cheekbones and large yellow eyes, with irises significantly larger than those of humans. When open they dominate the face, like those of a cat or lemur. The ears of the Na'vi are long and pointed and are able to swivel around much like that of a dog or a cat. The mouth is also large, but similar to a human's, with a faint cat-like bifurcation of the upper lip. The nose also faintly resembles that of a cat's, but this is only visible in close-ups. The teeth are white, with pronounced canines, upper and lower. The Na'vi species do obviously eat meat, but they are assumed to be generally omnivorous. The Na'vi have long, semi-prehensile tails. A complex pattern of iridescent dots and lines, mostly symmetrical, runs over the body, seemingly following the lines of the nervous or circulatory system. These are bioluminescent chromatophores, and they glow in the dark like fireflies. Na'vi have hair only on their heads, eyelashes and the very ends of their tails, and what people often mistake for a large braid is hair that covers an external part of their nervous system. === Queue === [[File:Queue.jpg|right|400px|A Na'vi/Ikran connection]] The Na'vi (and almost all other animal life on [[Pandora]]) anatomy includes a Neural queue which is similar in appearance on the Na'vi to long braided human hair, but is in fact an extension of their nervous system. It may look like that because the Na'vi braid it or because they have evolved the normally separate neural whip (as the structure is called on animals) pieces, as on most all over animals, into one. It is used to form ''Tsaheylu'', a connection with other living things, like other animals that possess a neural whip or antennae (such as the [[Direhorse|Pa'li]] and the [[Mountain Banshee|Ikran]]) and plants such as the [[Tree of Voices]]. This queue looks like a long braid, with many little pink, hairy, worm-like neural fibers on the end. The Na'vi use this organ to establish a neural-level connection to nearly any part of the [[Pandora]]n ecosystem. This connection is total, so both partners are in full control of the connected beings. The connection can serve many purposes, but is mostly used to enable a Na'vi rider to command his or her mount with his or her mind and with apparent little effort, and without use of their hands, which frees those up to use a weapon. This also enables her/him to use the mount's sensory organs. This also means that a Na'vi rider feels the pain when the connected animal is being hurt. In the case of communication with plant life, the vast network of connected nodes (plants) serves as a biological memory for Na'vi ancestors, and perhaps much more. The bonding of queues, ''Tsaheylu'', with an [[Mountain Banshee|Ikran]] is a rite of passage that all young Na'vi must endeavour. It is known as ''Iknimaya''. The bond is one that lasts for a lifetime after the first flight has occurred. The Na'vi connect their queues during mating to create a strong emotional lifelong bond. === Anatomical features === * Smooth skin is iridescent, cyan color. Long, sweeping tails. High cheekbones, feline ears and large amber coloured eyes. Bioluminescent markings aid in identification and mood display. Average life span is similar to that of a human. * Despite skin color, Na'vi have red blood (possibly because they are carbon-based life forms). * Waist is narrow and elongated. The shoulders are very wide, creating a V-shaped upper back. The neck is long and body slender. Musculature sharply defined, giving no sense of emaciation despite thin proportions. * Skeleton is reinforced with naturally occurring carbon fiber. Average male is 3 meters (9.8 feet) tall, females slightly smaller. * Three long fingers plus opposable thumb on hands; four toes on feet. It should be noted that the Na'vi/human hybrid [[Avatar]]s have five digits on both hands and feet. * Highly evolved nervous system includes a "Queue" which resembles a long, rather ostentatious hair braid. This seemingly conventional braid actually sheathes a remarkably intricate system of neural tendrils that can be connected to similar structures of other life-forms. See Queue. * They have roughly four times the strength of the average human. * Reproduction mechanics similar to humans and other Terran mammals. The Na'vi are fundamentally different from many other [[Pandora]]n mammals: * They only have four limbs, while many other medium-to-large-bodied animals have a total of six limbs. * They have only a single pair of eyes, while most other beings have two pairs of eyes, one primary set and another, smaller set. * Nearly other animals have two nerve clusters extending backward from the head, while the Na'vi only have a single nerve cluster located in their queue. * Many animals possess twin air intakes on the shoulders that supply air and keep their internal body temperature down, while the Na'vi possess no such structures. So we may conclude that the Na'vi either diverged a long time ago from the common Pandoran evolution tree, or in fact they are outsiders to this world. This latter theory is supported by the fact that the Na'vi and the humans have so much in common, including such rituals as kissing or the covering of the genital areas. However, the queue present in all Na'vi contradicts this theory. They presumably share a common ancestor with [[Prolemuris|Prolemures]], which also have hair and a single pair of eyes.
