How do the na vi clans differ in the avatar series?

The provided evidence discusses EVE Online, a space-based MMORPG game, which is completely unrelated to the Avatar series or the Na'vi alien species. There is no information in the given source about Na'vi clans, their differences, or any details from James Cameron's Avatar films. To properly answer your question about Na'vi clan differences in the Avatar series, I would need verified evidence from sources discussing the Avatar franchise, such as information about the Omatikaya, Metkayina, or other Na'vi clans featured in the films.
