In ecology, crypsis is the ability of an animal or a plant [1] to avoid observation or detection by other animals. It may be a predation strategy or an antipredator adaptation . Methods include camouflage , nocturnality , subterranean lifestyle and mimicry .
The following species belong in the genus Crypsis, according to contemporary taxonomic treatments: [2] [10] [11]. Crypsis aculeata – from Portugal and Mauritania to Korea; Crypsis acuminata – from Turkey to Kazakhstan
There are many methods of achieving crypsis. These include, resemblance to the surroundings, disruptive coloration, eliminating shadow, self-decoration, cryptic behaviour, motion camouflage, changeable skin appearance, countershading, counter-illumination, transparency, and silvering to reflect the environment. Many species are cryptically ...
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. Camouflage in large bodies of water differs markedly from camouflage on land. The environment is essentially the same on all sides.
Camouflage is the concealment of animals or objects of military interest by any combination of methods that helps them to remain unnoticed. This includes the use of high-contrast disruptive patterns as used on military uniforms, but anything that delays recognition can be used as camouflage.
A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading.
Crypsis has two distinct meanings in biology: organisms that hide themselves: crypsis; organisms that are difficult to distinguish: crypsis (taxonomy) See also
Studies evaluating the role of crypsis on herbivory measure leaf quality, such as nitrogen and protein levels, water content, etc. [4] Ehleringer et al. examined nitrogen levels, as an indicator of protein status, of mistletoe and their host (Acacia, Cassia, Casuarina, Ceriops, and Eucalyptus) to determine if mimicry reduced herbivory in the plant.
