Disruptive Colouration and Perceptual Grouping [PDF]
PLoS ONE, 2014 Camouflage is the primary defence of many animals and includes multiple strategies that interfere with figure-ground segmentation and object recognition.

Dissociating the effect of disruptive colouration on localisation and identification of camouflaged targets [PDF]
Scientific Reports, 2018 AbstractDisruptive camouflage features contrasting areas of pigmentation across the animals’ surface that form false edges which disguise the shape of the body and impede detection. In many taxa these false edges feature local contrast enhancement or edge enhancement, light areas have lighter edges and dark areas have darker edges.

Disruptive colouration in reef fish: does matching the background reduce predation risk? [PDF]
Journal of Experimental Biology, 2017 ABSTRACT Animals use disruptive colouration to prevent detection or recognition by potential predators or prey. Highly contrasting elements within colour patterns, including vertical or horizontal bars, are thought to be effective at distracting attention away from body form and reducing detection likelihood.

Scorpionfish adjust skin pattern contrast on different backgrounds [PDF]
Ecology and EvolutionThe two scorpionfish species Scorpaena maderensis and S. porcus are well camouflaged ambush predators that rapidly change body colouration to adjust to background colour in less than 1 min.

Aposematic signaling and seasonal variation in dorsal pelage in a venomous mammal [PDF]
Ecology and Evolution, 2021 In mammals, colouration patterns are often related to concealment, intraspecific communication, including aposematic signals, and physiological adaptations.

Factors Driving Background Choice in Scorpionfish [PDF]
Ecology and EvolutionFor a successful hunt, marine ambush predators such as scorpionfish need to be well camouflaged to deceive their prey. When the natural environment is heterogeneous, one strategy to maintain camouflage is choosing backgrounds to achieve better crypsis ...

Camouflage Using Surface Disruption: The Importance of Corners Versus Edges [PDF]
Ecology and EvolutionDisruptive colouration is a common mode of camouflage used by predators and prey to conceal their body contours. However, it is unclear how disruptive colouration hinders the detection and recognition of three‐dimensional (3D) body shapes.

Entomologia Experimentalis Et Applicata, 2023 AbstractCryptic colouration is an adaptative mechanism against predators. Colour patterns can become cryptic through background matching and disruptive colouration, which breaks up the outlines of an animal because the pattern does not coincide with the shape and outline of the animal's body.

PMEL is involved in snake colour pattern transition from blotches to stripes [PDF]
Nature CommunicationsCorn snakes are emerging models for animal colouration studies. Here, we focus on the Terrazzo morph, whose skin pattern is characterized by stripes rather than blotches. Using genome mapping, we discover a disruptive mutation in the coding region of the

Interactions between background matching and disruptive colouration: Experiments using human predators and virtual crabs [PDF]
Environmental Epigenetics, 2015 Abstract Interactions between disruptive colouration and the match between prey and background spot size were manipulated in two experiments that used time taken by human ‘predators’ to find artificial prey (virtual crab morphs) against heterogeneous backgrounds as a measure of the their camouflage.
