            (cornea) of the eye, start to release a yellowish dye (pigment). This pigment
            covers the eye and acts as a filter reducing the intensity of light, which
            enables the fish to see more accurately. In dark waters, this pigment
            disappears and the eye receives the maximum possible amount of light. 48
                It is obvious that this system is a product of conscious design. These
            cells releasing or clearing pigments is regulated consciously and cannot be
            considered as a product of coincidence. It is an expression of the perfection
            in the creation of Allah that an irreducibly complex organ structure such as
            the eye should be equipped with such a flawless chromatic system.




                                       Design in the Rock Cactus
                                       Some plants are created with special properties for defence
                                       from plant-eating predators and rodents. Some of these plants
                                       display properties miraculously similar to the surrounding
                                       environment in which they grow. The best example of these
                                      similarities is found in the South African rock cactus.
                                    Due to drought, the surfaces of these plants are extremely
                                  wrinkled. When these wrinkles are filled with dust, it becomes
                              impossible even for humans to distinguish these plants from rocks. If it were
            not for this property, this plant would become an irresistible target for insects and rodents. Another
            speciality of the rock cactus is the fact that it blossoms with very brightly coloured flowers at the end
            of the season of drought. Since the majority of creatures are absent at that time, it reduces the risks
            brought about by the flowers, which could nullify the camouflage.
