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 .
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 ...
This is a behavioral form of detection avoidance called crypsis used by animals to either avoid predation or to enhance prey hunting. Predation risk has long been recognized as critical in shaping behavioral decisions.
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.
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.

Cryptic female choice is a form of mate choice which occurs both in pre and post copulatory circumstances when females in certain species use physical or chemical mechanisms to control a male's success of fertilizing their ova or ovum; i.e. by selecting whether sperm are successful in fertilizing their eggs or not.
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions.
When an insect looks like an inedible or inconsequential object in the environment that is of no interest to a predator, such as leaves and twigs, it is said to display mimesis, a form of crypsis. Insects may also take on different types of camouflage , another type of crypsis.
