The behemoth was a type of bioship in use by Species 8472.They were notably different from the battleships as they were far larger and contained several "arms" extending from the body at the front of the vessel. Like most vessels piloted by Species 8472, these ships contained a single pilot that controlled the bioship. Finally, a Behemoth was capable of creating a temporary rift into Fluidic space which allowed the bioship to move between two points in normal space creating a fast method of travel.
