first encountered on the planet Arbra, this immense, avian predator was noted for it unusual body structure. Resembling a huge crab, the slivilith's body was wide and flat, with a pair of reptilian wings sprouting from its shoulders. The underside of the slivilith was dotted with thick tentacles, which it used in place of arms. The wings of this creature were blue across the top, and creamy-white below. The rest of the body was greenish-blue, with the belly being the same white as the underside of the wings. Most of the galaxy considered the slivilith a myth, a belief that was emphasized by the holo-series The Voyages of the VSD Protector. Supporting this belief was the fact that only four sightings of living sliviliths have been recorded since the era of the Freedon Nadd Uprisings. Xenobiologists agreed that the slivilith was not a creature that could have evolved on its own, however. Many believed that the ancient Arkanians created them, while other held that the Sith Lords were responsible. In reality, it was later discovered, the slivilith was one of the Yuuzhan Vong's earliest attempts to create a living ship that could travel faster than light, for use in obtaining information on nearby galaxies. The slivilith project was eventually abandoned, but not before many were released into the void. The Hoojibs managed to learn than the slivilith on Arbra had traveled through space for many years before landing on Arbra. This information, when re-analyzed many years later, pointed out the startling fact that the Yuuzhan Vong had been experimenting with inter-galactic travel for more than 4,000 years.
