・Double-Tongued Dictionary: the camouflage or protective appearance of an insect or animal. Editorial Note: Crypsis includes the stripes of a zebra that permit individuals to blend with a herd, moths that take on bark-like coloring so they are indistinguishable on trees, non-venomous snakes evolved to look like venomous species, insects that look like twigs or leaves, and brightly colored frogs that falsely indicate to predators that they are poisonous.
・Wikipedia: In ecology, crypsis is the ability of an animal to avoid observation or detection by other animals. It may be either a predation strategy or an antipredator adaptation, and methods include camouflage, nocturnality, subterranean lifestyle, and mimicry. Crypsis can involve visual, olfactory (with pheromones) or auditory concealment. When it is visual, the term cryptic coloration, effectively a synonym for animal camouflage, is sometimes used, though many different methods of camouflage are employed by animals.
