Adaptive Coloration in Animals is a 500-page book, 10 by 7 inches (250 by 180 mm) in its first edition. It was published by Methuen (in London) and Oxford University Press (in New York) in 1940.
Animal coloration, readily observable, soon provided strong and independent lines of evidence, from camouflage, mimicry and aposematism, that natural selection was indeed at work. [ 6 ] [ 7 ] [ 8 ] The historian of science Peter J. Bowler wrote that Darwin's theory "was also extended to the broader topics of protective resemblances and mimicry ...
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 ...
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.

Warning coloration of the "Brazilian Skunk" in The Colours of Animals [P 5] The basic concept of warning coloration (aposematism, like the black and yellow pattern of a wasp) is approached very simply: When an animal possesses an unpleasant attribute, it is often to its advantage to advertise the fact as publicly as possible.
Cephalopod molluscs such as this cuttlefish can change color rapidly for signaling or to match their backgrounds. Active camouflage or adaptive camouflage is camouflage that adapts, often rapidly, to the surroundings of an object such as an animal or military vehicle. In theory, active camouflage could provide perfect concealment from visual ...
Hugh Bamford Cott in his 1940 book Adaptive Coloration in Animals described many instances of countershading, following Thayer in general approach [12] but criticising Thayer's excessive claim ("He says 'All patterns and colors whatsoever of all animals that ever prey or are preyed upon are under certain normal circumstances obliterative ...
Adaptive melanism has been shown to occur in a variety of animals, including mammals such as squirrels, many cats and canids, and coral snakes. Adaptive melanism can lead to the creation of morphs , a notable example being the peppered moth , whose evolutionary history in the United Kingdom is offered as a classic instructional tool for ...
