Dear Yukari,
This is indeed a Madrella, almost certainly Madrella ferruginosa. It is very difficult to photograph in situ as it is so well camouflaged against its bryozoan prey. An interesting feature of your animal are the white sausage-shaped objects on the back of the animal. In the close-up alongside you can see that they are a collection of tiny spheres and are in fact the egg masses of a parasitic copepod which must have taken up residence on the Madrella
Best wishes
Bill Rudman
