The Na'vi are observed to have fit, slender, and muscular bodies, likely due to their active lifestyles. Despite their cyan skin color, the Na'vi have red blood, utilizing an iron oxygen-transporting compound similar to hemoglobin.
James Cameron recently spoke with Empire for their January 2023 issue and was asked why he decided to make the Na'vi blue in Avatar. It turns out that there's not any grand reasoning behind the choice, it was simply the only colour he felt wasn't taken by other cinematic characters. “As for the colour: green was taken.
Pandora, whose atmosphere is inhospitable to humans, is inhabited by the Na'vi, 10-foot-tall (3.0 m), blue-skinned, sapient humanoids that live in harmony with nature. To explore Pandora, genetically matched human scientists control Na'vi-human hybrids called "avatars".
After an appropriate mate has been selected, the Na'vi couple will mate before Eywa, often at a sacred site such as the Tree of Voices. During the mating, the couple will connect queues in an act called tsaheylu.
The reference implies that a Na'vi's queue may be considered an intimate area of the body. Removing the queue of Pandoran wildlife has been shown to have severe effects. Despite this, It is unknown what would canonically happen if a Na'vi queue was cut off, but it is still implied to be serious.
But it turns out the 'hair sex' scene was never part of the theatrical cut at all, it was actually in the Avatar extended version that was released in 2010. The extended version is also included on home video, DVD and Blu-ray.
Na'vi are monogamous creatures and the process of their reproduction is similar to Terran mammals, as they do possess genitalia; however, though they nurse their young and possess belly buttons where they were once connected to an umbilical cord, the Na'vi are non-placental, thus the details of their internal biology ...
In Avatar, the Na'vi are an indigenous species that live on Pandora. They are humanoid in appearance and are 9 to 10 feet (2.7 to 3.0 m) tall, having pairs of eyes, ears, arms, legs and feet like humans, as well as a nose, a mouth, and expressions recognizable to humans.
Apparently, only Avatars do this in a 'regular' basis; although it's possible (by speculation, as this actually happens with many real native tribes across the globe) that the Na'vi do have a way of cleaning or brushing their teeth.
A deleted scene from the end of Avatar (2009) revealed that Neytiri was pregnant, so Neteyam was born shortly after the events of the original movie. In accordance with the sequel's timeline, Jake and Neytiri's son Neteyam is nearly 15 years old in Avatar: The Way of Water.
The Na'vi people on Pandora have an average height of 9 to 10 ft which is almost double the height of the humans. The Na'vi people taller than humans because of the low gravity of Pandora. Additionally, the Na'vi people have only four fingers while the Avatars have 5 fingers.
The average Na'vi life span is longer than that of a human — approximately 30% longer — though they mature more rapidly. Na'vi skin is smooth, iridescent, and cyan in color accentuated with slightly darker cyan stripes.
All of the Na'vi that we've witnessed so far live in warm tropical environments. Perhaps dark hair is a natural trait beneficial for this type of climate (similar to how most dark-skinned people come from equatorial regions). We know Pandora has a colder polar environment as well.
Jake Sully, ex-Marine, is recruited into the RDA's Avatar program after his scientist twin-brother, Tommy, is killed. Since Jake and Tommy share identical DNA make-up, Jake is able to step into his deceased brother's role as an Avatar driver.
Her father is not a father, her father is another mother, Eywa, the Great Mother, the sentient life force of Pandora itself that exists in all things there, but is rarely understood. So essentially yes, Kiri was born from Eywa just like Anakin Skywalker was allegedly conceived by the Force itself and its midichlorians.
In Cameron's script she's introduced with the descriptor "in human age she would be 18," but that raises as many questions as it answers. As with the math that leads to Jake being 28, Neytiri's birth in the Earth calendar year 2136 and the film's setting in 2154 add up to make her 18, but that's by Earth standards.
The Na'vi are monogamous creatures that mate for life. Na'vi reproduction is similar to that of placental mammals on Earth. A Na'vi female will typically produce from one to ten offspring, often spaced widely apart in time. Na'vi females have two breasts, and nurse their infants for up to four months.
When Neytiri was 18 years old in 2154, she met Jake Sully in a Pandoran forest, rescuing him from a pack of viperwolves. Neytiri became his teacher in the ways of the Na'vi. Despite her prior engagement to Tsu'tey, Jake and Neytiri fall in love and consummated their relationship beneath the Tree of Voices.
Avatar - The Na'vi queue appears as a long braid, but the hair actually encases an intricate system of neural tendrils. These tendrils can be used to connect to a similar structure of other life forms, like the direhorse and mountain banshee, which after connecting can be controlled by the Na'vi.
No, Avatar: The Way of Water doesn't have an extra scene during or after the credits. We don't get any Easter eggs or a "Jake Sully will return" message either, it just cuts to the studio logo.
