The zoologist Hugh Cott had the final word in Adaptive Coloration in Animals (1940), a definitive synthesis of everything known about camouflage and mimicry in nature. Cott ruffled fewer feathers [than Trofim Lysenko or Vladimir Nabokov ], and his well-organized and unfanatic ideas proved militarily effective, even under the scrutiny of ...

He describes it as a device "perhaps unrivalled" for effective concealment, and points out that it is brought about and depends on "highly ...
In 1940, Hugh Cott wrote a compendious study of camouflage, mimicry, and aposematism, Adaptive Coloration in Animals. [6] By the 21st century, adaptation to life in cities had markedly reduced the antipredator responses of animals such as rats and pigeons; similar changes are observed in captive and domesticated animals.

Thayer's 1902 patent application. He failed to convince the US Navy. The English zoologist Edward Bagnall Poulton, author of The Colours of Animals (1890) discovered the countershading of various insects, including the pupa or chrysalis of the purple emperor butterfly, Apatura iris, [2] the caterpillar larvae of the brimstone moth, Opisthograptis luteolata [a] and of the peppered moth, Biston ...
Animals use colour to advertise services such as cleaning to animals of other species; to signal their sexual status to other members of the same species; and in mimicry, taking advantage of the warning coloration of another species. Some animals use flashes of colour to divert attacks by startling predators. Zebras may possibly use motion ...
Hugh Cott, author of the 1940 Adaptive Coloration in Animals, [6] followed by many other researchers, conflated distractive markings with disruptive coloration. [2] [3] Both mechanisms require conspicuous marks. However, the two mechanisms are different, and according to Dimitrova require different kinds of marking.
