A shrimp moves undisturbed along the
                                                     surface of a sea anemone. The trans-
                                                     parency of these small crustaceans is
                                                     extraordinary, because in most trans-
                                                     parent animals some major part of the
                                                     body still remains visible. For example,
                                                     most cannot manage to conceal their
                                                     digestive systems and the food con-
                                                     tained inside them. In some species,
                                                     only the tail and a part of the pincers
                                                     are coloured. These small details of
                                                     colour are useful in enabling the
                                                     shrimp to "disappear"; the contrast be-
                                                     tween the transparent parts and the
                                                     colourful markings is so pronounced
                                                     that would-be predators are drawn to
                                                     the markings themselves and are not
                                                     able to perceive the over-all outline of
                                                     the animal. 42
