Yammosk
this Yuuzhan Vong bio-creation was known among the elite warrior class as the war coordinator. The creature, with its bulbous head and array of tentacles, served to coordinate all activities of an invasion fleet toward a single goal. The creation of the first yammosk took many centuries, but in the end the creature proved to be a valuable asset. It could coordinate landing operations, starfighter battles, and even full-scale seiges. It had a virtually limitless supply of energy. The creature's only solid bodily structure was a single tooth, hidden with boneless flesh. The tooth was used to bury itself into a landing area, and was driven against the ground with incredible force. Eventually, it could break through even rock and ice, and the yammosk would then insinuate itself into the created crevasse and begin coordinating the invasion forces. Any enemy ships that got too close to the yammosk's position would be rendered inoperable by the intense energy the creature used to bind the Yuuzhan Vong forces together. Like most Yuuzhan Vong technology, the yammosk kept track of other Yuuzhan Vong starships by tracking their unique gravitic signatures. The only drawback of the yammosk was that, if it were ever severely injured or destroyed, the Yuuzhan Vong war force would be without any guiding force and would collapse in chaos. A Yuuzhan Vong prefect or other ranking official could commune with the yammosk by gently touching the thick, blue vein that ran between its eyes. Once the yammosk was entrenched in its new position, it could spawn a second yammosk to assist in the establishment of the next Yuuzhan Vong base. The parent yammosk would form a mental link with the offspring, transferring all knowledge it would need to act as the next war coordinator. However, the immature yammosk still had to grow strong, and the Yuuzhan Vong discovered that they grew faster if they were in contact with living bodies. Thus, the Yuuzhan Vong began capturing beings and forcing them to remain in the nutrient vats with the yammosk, giving it ready contact with life-energies. One additional benefit of this contact was that the yammosk could sense the presence of the Force, which allowed the Yuuzhan Vong to recognize the presence of a Jedi Knight in their midst. After the New Republic began to search out and destroy the yammosk at the heart of an invasion fleet, the Yuuzhan Vong began to train their pilots to act without a yammosk's guidance, giving the pilots more authority over the actions of their ships in case a yammosk was destroyed.
