Sound gross. It is a highly useful camouflage.The type of camouflage a species will develop depends on several factors: The environment in which it lives. This is usually the most important factor. The physiology and behavior of an animal. Animals with fur need different camouflage than those with feathers or scales. Likewise, animals who live in groups use different camouflage techniques than those that are solitary. If the animal is preyed upon, then the behavior or characteristics of its predator can influence how the camouflage develops. For example, if the predator is color blind , then the animal will not need to match the color of its surroundings. Animals produce colors in two ways: Biochromes — natural microscopic pigments that absorb certain wavelengths of light and reflect others, creating a visible color that is targeted towards its primary predator. Microscopic physical structures, which act like prisms to reflect and scatter light to produce a color that is different from the skin, such as the translucent fur of the Polar Bear , which actually has black skin. Camouflage coloration can change as well. This can be due to just a changing of the seasons, or it can be in response to more rapid environmental changes. For example, the Arctic fox has a white coat in winter, and a brown coat in summer. Mammals and birds require a new fur coat and new set of feathers respectively, but some animals, such as cuttlefish , have deeper-level pigment cells, called chromatophores , that they can control. Other animals such as certain fish species or the nudibranch can actually change their skin coloration by changing their diet. However, the most well-known creature that changes color, the chameleon , usually does not do so for camouflage purposes, but instead to express its mood. Beyond colors, skin patterns are often helpful in camouflage as well. This can be seen in common domestic pets such as tabby cats , but striping overall in other animals such as tigers and zebras help them blend into their environment, the jungle and the grasslands respectively. The latter two provide an interesting example, as one's initial impression might be that their coloration does not match their surroundings at all, but tigers' prey are usually color blind to a certain extent such that they cannot tell the difference between orange and green, and zebras' main predators, lions , are color blind. In the case of zebras, the stripes also blend together so that a herd of zebras looks like one large mass, making it difficult for a lion to pick out any individual zebra. This same concept is used by many striped fish species as well. Among birds, the white "chinstraps" of Canada geese make a flock in tall grass appear more like sticks and less like birds' heads. Mimicry Main article: Mimicry Mimicry describes a situation where one organism, the mimic, has evolved to share common outward characteristics with another organism, the model, through the selective action of a signal-receiver. The model is usually another species, or less commonly, the mimic's own species, including automimicry, where one part of the body bears superficial similarity to another. The signal-receiver is typically another intermediate organism, e. As an interaction , mimicry is always advantageous to the mimic and harmful to the receiver, but may either increase or reduce the fitness of the model. The distinction between mimicry and camouflage is arbitrarily defined in that the model in camouflage is not another organism; the arbitrary nature of this distinction between the two phenomena can be seen by considering animals that resemble twigs, bark, leaves or flowers, in that they are often classified as camouflaged a plant does constitute the "surroundings" , but sometimes classified as mimics a plant is also an organism. The more general category that encompasses such examples, therefore, is crypsis. Though mimicry is most obvious to humans in visual mimics, they may also use olfactory smell or auditory signals, and more than one type of signal may be employed. This type of camouflage, known as background matching, allows them to lie on the bottom of the seabed without being spotted. It is a highly useful adaptation. Some other animals have a type of seasonal camouflage. This includes the snowshoe hare, whose fur turns white in winter to match the surrounding snow. During summer, the animal's fur turns brown to match the surrounding foliage. The stripes of a zebra's coat , for example, create a disruptive pattern that is confusing to flies, whose compound eyes have trouble processing the pattern. Disruptive coloration is also seen in spotted leopards, striped fish, and black-and-white skunks. Some animals have a particular type of camouflage called a disruptive eye mask. This is a band of color found on the bodies of birds, fish, and other creatures that conceals the eye, which is usually easy to spot because of its distinctive shape.
