Since the Vorlon transport-class ship was docked at Babylon 5 for a great deal of time, we were able to learn more about it than any other type of Vorlon technology. Apparently, this ship not only contains an organic hull, it is also aware of its surroundings, almost sentient in some aspects. It also has the ability to reshape it's hull in a manner which we have never seen before. They are often attached to their 'owners,' and can often protect them if necessary. The rest of its secrets will remain a mystery to us...
