The concealing pattern in this fish was most remarkable, and the animal appeared to contain numerous holes, id) Individual on a black and white background, consisting of 5 mm circles. (From photo- graphs of Mast, 1914.) Carcharhinns glaucusâutilize countershading to maximal effect. Of equal interest are examples of inverted countershading, as in the pelagic snail Glaucus atlanticum which hangs belly uppermost from the surface film, and of lack of countershading, as in the shark sucker or remora {Echeneis naucrates) which attaches itself to larger fish with any side uppermost. Superimposed frequently upon countershading is a pattern of disruptive coloration in which the body form is broken up by irregular patches of contrasting colours. This is well seen in the disruptive phases of many reef.
