Defining Disruptive Coloration and Distinguishing Its Functions [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2009 Disruptive coloration breaks up the shape and destroys the outline of an object, hindering detection. The principle was first suggested approximately a century ago, but, although research has significantly increased, the field remains conceptually unstructured and no unambiguous definition exists.

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.

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,

Coincident Disruptive Coloration [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2009 Even if an animal matches its surroundings perfectly in colour and texture, any mismatch between the spatial phase of its pattern and that of the background, or shadow created by its three-dimensional relief, is potentially revealing. Nevertheless, for camouflage to be fully broken, the shape must be recognizable.

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 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,

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.

Crypsis Through Disruptive Coloration in an Isopod [PDF]
Proceedings of the Royal Society of London Series 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.

Cephalopod dynamic camouflage: bridging the continuum between background matching and disruptive coloration. [PDF]
Philos Trans R Soc Lond B Biol Sci, 2009 Individual cuttlefish, octopus and squid have the versatile capability to use body patterns for background matching and disruptive coloration. We define—qualitatively and quantitatively—the chief characteristics of the three major body pattern types used for camouflage by cephalopods: uniform and mottle patterns for background matching, and disruptive ...

Disruptive coloration elicited on controlled natural substrates in cuttlefish,Sepia officinalis [PDF]
Journal of Experimental Biology, 2007 SUMMARYCephalopods are known for their ability to change camouflage body patterns in response to changes in the visual background. Recent research has used artificial substrates such as checkerboards to investigate some specific visual cues that elicit the various camouflaged patterns in cuttlefish.
