New Atlantis The mechanism and the conditions for the change in colouration were made clear through the beautiful investigations of Keeble and Gamble, on the colour-change in crustaceans. Darwin and Modern Science This was in no sense owing to any far-fetched application of protective colouration; but to the remarkable skill the animals possessed in concealing themselves behind apparently the scantiest and most inadequate cover. The Land of Footprints In cases of "cryptic resemblance to surroundings" the shape, colouration, or markings are such as to conceal an animal by rendering it difficult to distinguish from its immediate environment. The Naturalist in Nicaragua The adults, however, vary greatly one from another in colouration. The Human Side of Animals In the whole realm of Nature there is nothing more wonderful than this matter of protective colouration. The Human Side of Animals Their formidable means of defence makes for them the obscure colouration of other dusk-roaming mammals unnecessary, as they do not need concealment.
