In ecology, crypsis is the ability of an animal or a plant [1] to avoid observation or detection by other animals. It may be part of a predation strategy or an antipredator adaptation . Methods include camouflage , nocturnality , subterranean lifestyle and mimicry .
Anti-predator adaptation in action: the kitefin shark (a–c) and the Atlantic wreckfish (d–f) attempt to prey on hagfishes. First, the predators approach their potential prey. Predators bite or try to swallow the hagfishes, but the hagfishes have already projected jets of slime (arrows) into the predators' mouths.
A wide range of animals, e.g. lizards, birds, rodents, and sharks, behave as if dead as an anti-predator adaptation, as predators usually take only live prey. [ 15 ] In beetles, artificial selection experiments have shown that there is heritable variation for length of death-feigning.
Müllerian mimicry, too, in which two or more distasteful species that share one or more predators have come to mimic each other's warning signals, was clearly adaptive; Fritz Müller described the effect in 1879, in an account notable for being the first use of a mathematical argument in evolutionary ecology to show how powerful the effect of ...
It is often combined with other methods of crypsis including background colour matching and countershading; special cases are coincident disruptive coloration and the disruptive eye mask seen in some fishes, amphibians, and reptiles. It appears paradoxical as a way of not being seen, since disruption of outlines depends on high contrast, so the ...
The walking leaf insects from the Indo-Pacific region resemble tree leaves in appearance and posture.In biology, mimesis (from ancient Greek μίμησις mímēsis, "imitation") [1] is a form of crypsis where living creatures mimic the form, colour and posture of their surroundings to avoid being noticed from their surroundings by predators depending on sight.

When he was casting Prey — the new Predator prequel set three centuries before Arnold Schwarzenegger tangled with the deadly E.T. — director Dan Trachtenberg insists the idea of hiring a ...
Leafy sea dragon avoids recognition by predators, with alga-like coloration, protuberances and behaviour. Underwater camouflage is the set of methods of achieving crypsis—avoidance of observation—that allows otherwise visible aquatic organisms to remain unnoticed by other organisms such as predators or prey.
