The hanging frabooball split from its ancestor and now has a symbiotic relationship with the symbiomoeba that lives in its guts. It hangs on the walls of the cave, away from predators, and takes in minerals to feed its microbes. To hang it uses its merged antennae, the ends produce an adhesive so there is no danger of falling. To move up or down the wall the antenna can slowly be adjusted by moving the ends, moving on the ground is left to a pair of specialized kickers, derived from ends at the base of the antennae. It may nibble the occasional corpse to keep up with certain nutritional needs that aren't met by the symbiomoeba inside it.
