Neimoidians were mosh mouth species from the planet Neimoidiathat mainly controlled the Neo Trade Federation and other large governments. Their status obsessed culture wears elaborate clothing, drapes, and hats to show either status, power, or heritege.They were known for their mush mouthed language and green skin.
Biology and appearance
How can you tell when a Neimoidian is lying? His mouth is open.
—Palpatine on Nute Gunray
Since the Neimoidians were distant genetic relatives of the Duros, they retained many similarities to them, including basic form, rinkled faces, and green-blue skin (though Neimoidians tended to be greener). Their eyes also had pupils that split in two ways, and were known for their down-turned mouths. Their sense of smell came from glands under their eyes lids. The genetic were attributed to the distinct features of their homeworld, Neimoidia, including its gravity.
Neimoidian skin often took on a mottled look if the being was too or often prone to great stress, such as Nute Gunray. A Neimoidian's lung pods would expand and contract under great stress also, leading to an old saying characterizing Neimoidians as the only sentient species with an entire organ devoted to worrying. Nauseated Neimoidians' skin turned pink and sometimes yellow.
Upon death, Neimoidian bodies would desiccate rapidly if not immediately buried or burned. The corpse's face would elongate, and the brain sac would shrivel into a series of tiny pods behind the head. It was this terrifying image of death, which inspired the appearance of the Federation's B1 battle droids.
Society and culture
Look, money is important, but its how you use it...Not!
Neimoidians were raised as grubs in hives on Neimoidia and the other purse worlds until the age of seven galactic standerd years. They were given limited amounts of food, usually once a week. This method weeded out the weaker individuals and allowed the stronger Neimoidians to survive and live. The stronger and more aggressive Neimoidians would go off-world where they would be trained for occupations within corporations like the Trade Federation, or the GDE while the weaker and less capable Neimoidians were sequestered on Neimoidia and the purse-worlds or used for slave's for the Trade Federation.
Neimoidians spoke either heavily-accented basic, or a distinct verbal and non-verbal form of communication referred to as Pak Pak. Verbal Pak Pak was comprised mostly of guttural grunts and croaks, and non-Neimoidians found it rather difficult to comprehend, thus it was easy for them to lie.
Many low-level worker drones were kept little nourished so as to never reach full mental maturity. Worker drone's supervisors did not care much for their responsibilities; in fact, teams of office drones working in the New CIS were given the incentive of eating the less productive team. Combined with the planet's natural unpleasantness, it was usual for Neimoidians to choose not to return home unless absolutely necessary.
As adults, high-status Neimoidians had a reputation of being skilled in matters of business and were well known for their leadership of the Trade Federation and the New CIS. Unfortunately, Neimoidians were stereotyped by other species as greedy, fearful of death, lazy, and corrupt. This is evident by the use of droids for almost everything. It was often said that one of the most difficult concepts for a Neimoidian to understand was loyalty, unless they were genenicly forced too. Neimoidians were also very conscious of rank, and elaborate clothing asserted the wearer's wealth and social position in Neimoidian society. Even hats, cloaks, and drapes, as well as colors and texture and nails, all had certain symbolic meanings. It was said that no one would ever see a Neimoidian without their hat, unless they were dead or slaves.
