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 .
The coloration of the Papuan frogmouth Podargus papuensis, its outline disrupted by its plumage, its eye concealed in a stripe, is an effective anti-predator adaptation. Disruptive coloration (also known as disruptive camouflage or disruptive patterning ) is a form of camouflage that works by breaking up the outlines of an animal, soldier or ...
In the words of camouflage researchers Innes Cuthill and A. Székely, the English zoologist and camouflage expert Hugh Cott's 1940 book Adaptive Coloration in Animals provided "persuasive arguments for the survival value of coloration, and for adaptation in general, at a time when natural selection was far from universally accepted within ...
Cott's method is to provide a large number of examples, illustrated with his own drawings or photographs, showing animals from different groups including fish, reptiles, birds and insects, especially butterflies. The examples are chosen to illustrate specific adaptations. For example, the fish Chaetodon capistratus is described as follows: [P 2]
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.
In ecology, crypsis is the ability of an animal or a plant to avoid observation or detection by other animals. It may be a predation strategy or an anti-predator adaptation. Methods include camouflage, nocturnality, subterranean lifestyle and mimicry. Crypsis can involve visual, olfactory (with pheromones), or auditory
Texas A&M AgriLife Extension Service was formally established in 1915 after the 1914 passing of the Smith-Lever Act and in conjunction with Texas A&M University.Originally named Texas Agricultural Extension Service, then later Texas Cooperative Extension, the name Texas AgriLife Extension Service was adopted on January 1, 2008.
It is widely accepted that mimicry evolves as a positive adaptation. The lepidopterist and novelist Vladimir Nabokov however argued that although natural selection might stabilize a "mimic" form, it would not be necessary to create it. [23] The most widely accepted model used to explain the evolution of mimicry in butterflies is the two-step ...
