Background matching, disruptive coloration, and differential use of microhabitats in two neotropical grasshoppers with sexual dichromatism [PDF]
Ecology and Evolution, 2020 Cryptic coloration is an adaptative defensive mechanism against predators. Color patterns can become cryptic through background coloration‐matching and disruptive coloration.

Biomimetic chameleon soft robot with artificial crypsis and disruptive coloration skin [PDF]
Nature Communications, 2021 Realizing an artificial camouflage device with a high spatial resolution by adapting to the surrounding environment in real-time is a challenging task, mainly associated with device fabrication and integration with sensor and control circuits.

Disruptive coloration and binocular disparity: breaking camouflage [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2019 Many species employ camouflage to disguise their true shape and avoid detection or recognition. Disruptive coloration is a form of camouflage in which high-contrast patterns obscure internal features or break up an animal's outline. In particular, edge enhancement creates illusory, or ‘fake’ depth edges within the animal's body.

Background-matching and disruptive coloration, and the evolution of cryptic coloration [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2005 Cryptic prey coloration typically bears a resemblance to the habitat the prey uses. It has been suggested that coloration which visually matches a random sample of the background maximizes background matching. We studied this previously untested hypothesis, as well as another, little studied principle of concealment, disruptive coloration,

Empirical tests of the role of disruptive coloration in reducing detectability [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2007 Disruptive patterning is a potentially universal camouflage technique that is thought to enhance concealment by rendering the detection of body shapes more difficult. In a recent series of field experiments, artificial moths with markings that extended to the edges of their ‘wings’ survived at higher rates than moths with the same edge patterns ...

Disruptive coloration, crypsis and edge detection in early visual processing [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2006 Many animals use concealing markings to reduce the risk of predation. These include background pattern matching (crypsis), where the coloration matches a random sample of the background and disruptive patterns, whose effectiveness has been hypothesized to lie in breaking up the body into a series of apparently unrelated objects.

Disruptive coloration provides camouflage independent of background matching [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2006 Natural selection shapes the evolution of anti-predator defences, such as camouflage. It is currently contentious whether crypsis and disruptive coloration are alternative mechanisms of camouflage or whether they are interrelated anti-predator defences. Disruptively coloured prey is characterized by highly contrasting patterns to conceal the body shape,

Crypsis through disruptive coloration in an isopod [PDF]
Proceedings of the Royal Society B: Biological Sciences, 1998 The white–spotted colour morph of the marine isopod Idotea baltica appears cryptic on the brown alga Fucus vesiculosus with its white–coloured epizoites Electra crustulenta and Balanus improvisus . This study shows that the crypsis of this coloration is achieved through disruptive coloration rather than through background matching.

Crypsis by background matching and disruptive coloration as drivers of substrate occupation in sympatric Amazonian bark praying mantises [PDF]
Scientific Reports, 2023 Background matching and disruptive coloration are common camouflage strategies in nature, but few studies have accurately measured their protective value in living organisms.

Disruptive coloration and habitat use by seahorses [PDF]
Neotropical Ichthyology, 2019 Predation avoidance is a primary factor influencing survival. Therefore, any trait that affects the risk of predation, such as camouflage, is expected to be under selection pressure.
