Pandoran biosphere

The Pandoran biosphere is a fictional habitat introduced in James Cameron's 2009 science fiction film Avatar. The ecology of the lush exomoon Pandora, which teems with a biodiversity of bioluminescent species ranging from hexapodal animals to other types of exotic fauna and flora, forms a vast neural network spanning the entire lunar surface into which the Na'vi 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 Na'vi are nearly defeated. Cameron utilized a team of expert advisors to make the various examples of fauna and flora as scientifically feasible as possible. In Avatar, the Na'vi are an indigenous species that live on Pandora. They are humanoid in appearance and are 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 Na'vi differ from humans in having blue striped skin, pointed and mobile ears, large eyes, catlike noses and 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 Na'vi 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, transferring electrochemical signals such as thoughts and memories. 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 when one of the main characters, Neytiri, was originally drawn, she had gills and other protuberances. In addition to feline features, the species were redesigned to seem more human so audiences could better relate to them.
