The Na'vi are a fictional indigenous species that live on the fictional world of Pandora in the movie Avatar. They look like humans. They have two eyes, ears, arms, and legs. They also have a nose, a mouth, and expressions that are similar to humans. The Na'vi are different because they have blue skin, pointed ears, huge eyes, and tails. They are also taller than humans. They have a smaller body frame. At the beginning, the Na'vi were meant to be more alien in their looks. Director James Cameron said that in the first drawing of the main character, "Neytiri", she had fins, gills, and cat-like features. The species was changed to look more like humans. This was so audiences could relate (feel closer and empathise) to them better. Cameron said that "Avatar" was more "science fantasy" than true science fiction. He said that he would explain in the novel why the Na'vi look like humans.
