Vangaak

The Vangaak is an aquatic trawler used by the Yuuzhan Vong for travelling underwater. The living craft's skeletal frame is composed from the tough Yorik Coral. Once the frame matures, it is seeded with a living organism called kera-boa which reproduces rapidly creating a semisentient protoplasmic colony which sprouts millions of long, microscopic tendrils which dangle below the craft. Even these tendrils are made to move together, they can propel the craft in any direction. After the kera-boa system has taken root, the vangaak is enveloped by hundreds of long, tough dull green scales supplied by the dora-mu, which an aquatic creature imported from the Yuuzhan Vong galaxy.

However those green scales do not die upon removal from the dora-mu because it can mold itself onto the vangaak's skeleton receive nutrition from the living craft. These scales are also able to withstand blaster bolts and are capable of healing. Also knobby projections that can control the craft sprout from the carapace. The Vangaal trawlers that appeared in the NJO novel Edge of Victory: Conquest were use to gather fish and other aquatic life. It travels largely submerged with only a broad flat dome that serves as a sensory device visible.

The vangaak feeds by opening a large maw at the front of the craft which can suck in fish. The water is filtered through thick, sticky strands of kera boa tendrils. Large organisms get caught in this web while smaller ones pass throug the kera boa tendrils into the vangaak's digestive membrane which fuels the craft. In the book Edge of Victory: Conquest, Vua Rapuung and Anakin Solo travelled to the Yuuzhan Vong base in one of these trawlers. Larger variants of the vangaak, can be used for aquatic combat with the adittion of specialised plasma projectors. They can also be used as sea-going troop transports and can board enemy vessels.
