Tentaculaks are a sapient species, notable for having numerous tentacles around their bodies for manipulation, which constantly wave about back and forth. The Tentaculak are not aligned with any particular affiliation, and thus operate independently. Their vessels are notably difficult to board and take down, as being a gas bag species lets them float around, through thousands of labyrinthine pathways; not only this but the actual Tentaculak body structure is incredibly thin, generally too thin for most individuals to squeeze through (although Stralks and Uu'taeris have no difficulty squeezing between the spaces). They also completely lack vocal chords, instead using their numerous tentacles as a form of complex sign language; it is so complex due to the sheer number of tentacles involved in any given word or sentence that is is notably difficult to properly translate using universal translators at this time.
Some Tentaculak have been exposed to the Chaos Legions' Hyper Evolutionary Virus, which transforms them into a Manipulator. These violent mutants aggressively convert more sapients into willing servants of the Chaos Legions, in particular not infected Tentaculak.
