Molleung Worm
this Yuuzhan Vong bio-creation resembled a huge annelid which could be used to serve a number of purposes. In space, they could be used as a living cofferdam. In the air, a molleung could discharge large cargoes from a transport ship to a ground installation. They were modified for use on yorik-trema landing craft, to deposit ground forces into enemy territory. A molleung worm could also be used to link underwater chambers.
