Pandoran biosphere

The fictional Pandoran biosphere, from James Cameron's Avatar, teems with a biodiversity of bioluminescent species ranging from hexapodal animals to other types of exotic fauna and flora. The Pandoran ecology forms a vast neural network spanning the entire lunar surface into which the Naʼvi and other creatures can connect. The strength of this collective consciousness is illustrated when the human invaders are defeated in battle by the Pandoran ecology, after the Naʼvi were nearly defeated. Cameron utilized a team of expert advisors in order to make the various examples of fauna and flora as scientifically feasible as possible.

In Avatar, the Naʼvi 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. The Naʼvi differ from humans in having blue striped skin, pointed and mobile ears, large eyes, catlike noses and teeth, tails, and hands each with three fingers and a thumb (hybrid avatars, on the other hand, retain the five-fingered hands of their human DNA). While taller than humans, they have narrower proportions in body frame. Their bones are reinforced with naturally occurring carbon fiber. The Naʼvi also have a distinctive tendril feature protruding from the back of their heads, surrounded by hair (resembling a long plait 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 Naʼvi were initially conceived to be more alien in appearance. Cameron recalled that when one of the main characters, Neytiri, was originally drawn, she had gills and other protuberances. In addition to feline features, the species was redesigned to seem more human so that audiences could better relate to it.
