 movie, they don't need to know about the hundreds of artists who slaved away at computers for years to make it. It's just: Do I like this story? Do I like the characters? I think Avatar will work that way."

Cameron explained his objective to seamlessly translate actor performances into computer-generated characters, saying, "It evolved from a couple of things: growing up on a steady diet of science fiction, imagining alien characters, and being ultimately dissatisfied with what was possible with makeup and prosthetics, with an actor having to be in the makeup chair for six hours a day. This technology isn't about replacing or marginalizing actors. It's about allowing actors to transform and empower them to be as creative as they want to be. And by the way, we did tall blue people with pointy ears here. But we could easily have done a straight human face if we'd wanted to ... If we had put the same energy into creating a human as we put into creating the Na'vi, it would have been 100 percent indistinguishable from reality."

Cameron hopes to explore the other moons in future sequels, books, and spin-offs.

While taller than humans, they have narrower proportions in body frame. Their bones are reinforced with naturally occurring carbon fiber. The Na'vi also have a distinctive tendril feature protruding from the back of their heads, surrounded by hair (resembling a long braid or queue

), feeding directly into the brain. This organ allows them to connect with other organisms around them, transferring electrochemical signals such as thoughts and memories to the trees, plants, and other creatures. In the original script, Cameron refers to these as "Jubilees" although the word is not used in the film and may be changed by the time the novel is published.
The Na'vi were initially conceived to be more alien in appearance. Cameron recalled that when one of the main characters, Neytiri, was originally drawn, she had fins, gills, and other protuberances. In addition to feline features, the species was redesigned to look more like humans so audiences could relate to them better.

According to Cameron, the appearance of the Na'vi character Neytiri had some specific inspirations and requirements: she was inspired by Raquel Welch

According to Entertainment Weekly, "The Na'vi can commune with animals on their planet by literally plugging their braid into the creatures' nerve systems. To become a warrior, a Na'vi must tame and ride a flying creature known as Ikran." The Na'vi also use this neural bonding system, called "tsaheylu", to mate

On religion, the chief and possibly sole deity of the Na'vi is a benevolent goddess known as Eywa. The Na'vi are able to "connect" to Eywa when they use their braids to connect to the Tree of Souls and other similar flora. Eywa is said to have a connection to all things Pandoran.

Fauna

James Cameron's core idea for the Avatars fictional creatures was for them to be "superslick and aerodynamic, and be like a race car with racing stripes". Neville Page worked on Avatar as the lead creature designer. He adapted Cameron's conceptions of the fauna into design that served three purposes: look expressive, function with animation technology, and be believable enough for audiences. He and creature designer Wayne Barlowe sought to base the design of Pandora's creatures on race cars, but they struggled to adapt the concept. Page drew on his education in automotive design, recognizing the irony that race cars were based on real-life animals in having "bone lines". Existing automotive designs drew from seashells, turtle shells, and insects, and the creature designers returned the design to the fictional creatures. They found the biggest challenge in designing most creatures to give them organic appearances since they lacked excessive skin texturing. Some creatures were also designed to have special breathing holes located in the trachea

 according to Cameron and the designers. However, even though they discussed the idea of the creatures being part of Pandora's "Worldmind", they preferred to interpret the creatures as having heightened instincts. Page explained, "Animals are hooked up to this planet. We're the ones who are detached.... The way I dealt with it was, We have so much rich [material] here to reference, that we don't have to dream up a whole new process of animal awareness."

The fictional moon has less gravity than Earth, so the creatures' larger sizes match their environment. Most Pandoran wildlife are hexapodal, or six-legged. Much of the fauna and flora are bioluminescent

    s. It is scientifically known as Equidirus hoplites. The Na'vi use the Direhorse to hunt. The Direhorse was conceived and designed by Cameron and Stan Winston Studios. The Direhorse is grey with blue stripes and stands thirteen feet (3.9 meters) tall, fourteen feet (4.2 meters) long. The Na'vi "break" a Direhorse by connecting the fleshy tip of their hair to the animal's antennae. Xenobiologists call this a neural whip. Once intertwined, the Na'vi rider can communicate motor commands instantly through the neural interface; however, this connection does not lead to a life-long, exclusive bond, as it does with the Mountain Banshee. Cameron described the creature as a "six-legged alien Clydesdale with moth-like antennae". The Direhorse uses its long tongue to eat the sap out of Pitcher Plants.
  • Mountain Banshee (Ikran in Na'vi) is an airborne predator who lives in mountainous territory on Pandora. Na'vi warriors attempt to bond with a Banshee, a dangerous and required rite of passage

They are four-winged creatures that, like the Leonopteryx and Direhorse, have a biologically produced carbon fiber flexing on the skin. Neytiri had a Banshee named Seze (translated from the language of the Na'vi roughly as "blue flower"). Page spent the most time designing the Banshee for the film so it would be convincing when it flew or perched. The designer said, "The hardest thing of all was having a Na'vi on top of it and flying it. You had to backwards engineer it. It was like designing and engineering an aircraft." Barlowe, who contributed to the Banshee's design, was influenced by manta ray

  • Great Leonopteryx (Toruk in Na'vi, meaning Last Shadow) is the apex airborne predator native to Pandora. It is scientifically known as Gavilandora maxima. The fierce beauty and nobility of the Leonopteryx gave the species a place in central Na'vi lore and culture. Leonopteryx are scarlet with black stripes and a midnight blue crest on top of the head and on the lower jaw. It is celebrated in dance, song, and with elaborate totems that symbolize both the fear and respect accorded to the creature. The Leonopteryx is considered crucial to the Na'vi sense of destiny and interconnectedness. Prior to the events of the film, it had only been tamed five times, and Neytiri tells Jake that the riders (Toruk Makto, Rider of Last Shadow) brought peace among the Pandoran tribes. Later, as an act to regain the Na'vi's trust, Jake became the sixth Toruk Makto. He managed to capture one by jumping on it from above from his Banshee, but released it after the battle with the humans ended, saying Toruk Makto was no longer needed. The Great Leonopteryx and the Banshee were designed with bright colors. Page based the colors on Earth's birds, poison dart frog

This massive, grazing creature travels in moderately large herds or packs of 10–20 animals. Avatar creature designer Yuri Bartoli explained to io9.com about the creature's colorful threat display: "Originally, the Hammerhead just had to be a huge creature, big enough that even a Thanator would think twice about attacking one. A threat display is meant to be seen, so it required bright colors that would stand out against its more muted body". It is moderately social, but also extremely territorial and hierarchical. A soft ungulate mouth is protected by a rigid, beak-like jaw structure. It is scientifically known as Titanotheris hammercephalis.

Their small, sloped skull is topped by this light-colored fan structure. This fan has an eye pattern on it similar to those found in Terran insects. A skin membrane hangs under the jaw and runs the length of the neck. Twin lines of dark hairlike bristles run down the Hexapede's back. The antennae are at the back at the head. As a threat display, the Hexapede flares up its twin membrane structure like a satellite dish and retracts both lips. It is scientifically known as Sexcruscervus caeruleus.

  • Thanator (Palulukan in Na'vi) is a large hexapodal land predator that is believed, by the RDA, to be the apex land predator. It is scientifically known as Bestiapanthera ferox. Cameron personally designed the creature. The Thanator is first seen when Jake wanders off into the jungle, and touches multiple Helicoradian leaves, and they retract to reveal a family of Hammerhead Titanotheres behind. The Thanator scares off the Titanotheres, then goes after him. Jake later escapes the Thanator by going over a waterfall. It is black with white fleshy skin under each hand.

  • The Hometrees (Kelutral in Na'vi) are great enough to house hundreds of clan members. The trees are honeycombed with natural hollows and alcoves in which the Na'vi sleep, eat, weave, dance, and celebrate their connection to Eywa. Adult Hometrees are more than 150 meters (492.1 feet) tall, and roughly 30 meters (98.4 feet) in diameter. The Omaticaya inhabit a Giant Hometree, standing roughly 460 meters (1509.1 feet) tall. A distinguishable feature of the movie landscape, the tree itself is central to the movie story arc. Like many sacred sites on Pandora, the Giant Hometree sits above a large deposit of unobtanium. It is destroyed by the humans using rockets and missiles, which leads to the Na'vi clans' alliance against the humans. It is not the only one on the planet though.
