Cape worms are segmented worms with a cape of living tissue attached just behind the head. This produces a lot of drag while swimming and so cape worms are rather clumsy and slow. What they lack in speed they make up for in camouflage. Curling completely under the cape when predators pass, the cape mimics the texture and brightness of surrounding objects and cancels all electrical emanations by creating a second wave of opposite phase.
