The bioship was an organic vessel that was used by Species 8472 and had a similar genetic makeup to their pilots. The bioships, and Species 8472 themselves, were resistant to assimilation by the Borg and carried an extremely powerful weapon that could destroy even Borg vessels easily. The bioships contained a series of vein-like conduits which carried electrodynamic fluid, possibly for use as an energy source.
Eight of these ships could collect and combine their firepower, using an energy focusing ship, which enabled them to fire a blast so powerful it could destroy a planet. When the Borg entered fluidic space, they were forced back by this resistance. Defense against these ships was found by the crew of USS Voyager, in the form of modified Borg nanoprobes.

- The Species 8472 bioships were created as a CGI model built by Foundation Imaging's senior supervising visual effects animator, Adam "Mojo" Lebowitz. Their two forms of weaponry were devised by Visual Effects Supervisor Ronald B. Moore and Visual Effects Coordinator Cheryl Gluckstern. (Cinefantastique, Vol. 29, No. 6/7, p. 95)
