Little Known Facts to Amaze and Confound Your Friends... RUBBERNECKIA The long-standing belief that unlimited rotary motion is impossible in animals has been shattered. It was, after all, a very reasonable assumption, because necks and other appendages turn only so far before bones and muscles begin to snap. Well, it seems that inside termite guts there resides a single-celled animal with a head that rotates constantly 30 times a minute. Since none of its membranes shear during rotation, we must infer that membranes are basically fluid structures rather than solids as supposed. The animal, called Rubberneckia, has a shaft running the full length of its body plus a motor of undetermined character. To make Rubberneckia even more bizarre, thousands of tiny, rod-like bacteria occupy long grooves on the cell's surface. Like galley slaves, the bacteria row with their flagella to keep Rubberneckia moving -- a curious symbiotic relationship.
