Lungworm

A Lungworm was a biotechnological creature shaped by the Yuuzhan Vong to supply air to to the gnullith worn with a vacuum ooglith, their equivalent of a spacesuit. Worn coiled on the wearer's back, it reached round over the shoulder to connect its mouth to the gnullith, and it could supply air for up to two hours&mdash;at which point, having run out of air itself, it would expire.
