Aquamotes are a recently (as of 5151:13) implemented form of transportation designed for sapient aquatic organisms like the Pithok. They consist of large cylindrical water-filled tanks which cross in parallel with terrestrial paths.
An Aquamote consists of an enclosed bulbous tank filled with oxygenated water. This water is dyed a form of light blue for unknown reason, and allows aquatic citizens of the Empire to locomote in terrestrial metropolises. The average Aquamote is equipped with glove ports, which allows the aquatic citizens to interact with the terrestrial, and a speaker/microphone system to allow verbal communication.
As of 5151:13, Aquamotes are still be connected to lakes, cities, and oceans around Known Space to allow Pithoks to locomote around the Empire’s vast borders.
