Study
Adaptive Coloration in Animals
Cott, Hugh B.
Methuen, 1940
A systematic survey of animal coloration, classifying concealment into background matching, disruptive coloration, countershading, shadow elimination and masquerade, illustrated throughout by the author’s own drawings and photographs.
- Studied in
- Animalia
- Sample size
- comparative survey with original illustration
Concealing coloration divides into distinct mechanisms that work in different ways, and disruptive coloration in particular was proposed as breaking up the perceived outline of a body rather than matching its surroundings.
What it means
The authors' reading, and ours. Where they differ, that difference is the point.
How the authors put it
Camouflage is not one thing. The categories are functionally distinct and should be distinguished when describing any particular animal.
How NatureHQ reads it
The book that set the categories this whole family still uses, and a good example of how far a framework can travel on argument alone. Cott had almost no experimental evidence for the distinctions he drew; they were argued from illustration and comparison, and it took sixty years for somebody to test the central one properly. That it held up is genuinely impressive.
- A 1940 survey arguing from illustration and comparison rather than from measurement or experiment.
- Written entirely from human visual judgement, which is the methodological problem the modern field is built around avoiding.
What this study is used for on NatureHQ
One study can inform several subjects. Here is everywhere this one is cited.
Disruptive coloration
Patterns that break up an animal’s outline protect it beyond simply matching the background. Artificial moths with markings touching the edge survived better than identical ones with the markings moved inside.
Countershading
Dark above and pale below does conceal: artificial prey with the gradient outlived uniform prey of the same average shade. But the pattern is so common that concealment need not be why any given animal has it.
Disruptive coloration
Disruptive markings are bold, and the boldness is the mechanism rather than a price paid for it: a faint mark makes no convincing false edge. Some strongly patterned animals are the hardest to pick out.
