Kera-boa
From Wookieepedia, the Star Wars wiki.
The Kera-boa was a gelatinous organism which was used by Yuuzhan Vong Shapers to cover the frame of a growing Vangaak.
Once attached to the vangaak frame, the kera-boa would reproduce rapidly, creating a semi-sentient protoplasmic colony which sprouted millions of long, microscopic tendrils that dangled below the craft. These tendrils were made to move together and could propel the craft in any direction.
It is unknown what became of the kera-boa after the war ended; though it can be assumed they were transplanted on Zonama Sekot where they would have joined the tampasi.
