The Geonosian race, often called Geos or bugs in clone trooper slang, was an insectoid species native to the planet Geonosis. Geonosians resided in catacomb-like hive colonies beneath the organic-looking spires.
The Nautolans, sometimes referred to as the Nautiloids, were an amphibious humanoid species from the planet Glee Anselm. Nautolans possessed physiology common to amphibious species, including low light vision and excellent swimming skills. They had smooth green, blue, or brown skin, and large black or dark maroon eyes with lids that were seldom used. They were capable of breathing underwater; however, unlike other water-based species, Nautolans did not experience difficulties on land.
