Reading Passage

Animal Camouflage 

A The theory of natural selection, proposed by Charles Darwin almost 150 years ago, hypothesizes that organisms with traits that give them a survival advantage tend to live: longer and produce more offspring. Over many thousands of years of evolution, those beneficial characteristics dominate the gene pool. Animals that use camouflage to conceal themselves from their enemies, predator and prey alike, provide a classic example of natural selection at work. Creatures with some type of protective coloring pass along the genes responsible, with each generation fine tuning them along the way, eventually providing the most effective coloring for their environment and lifestyle. Scientists have described four types of camouflage that animals use: background matching, disruptive coloration, countershading, and mimicry.

B From dirt-colored chipmunks and gophers to leaf-green praying mantises and tree frogs to ocean gray mackerel and sharks, all sorts of wildlife use background matching, also known as crypsis, to blend in with their surroundings. Some animals have the ability to alter their coloring as their environment changes seasonally or as they change locations. The arctic ox and the snowshoe hare both have white winter fur that matches the snow and ice around them, but a brown pelt in warmer weather blends in with their woodland environs. Some reptiles and fish can alter their surface appearance instantly as they move from place to place. The green anole lizard changes from green to brown as it travels among leaves and branches, whereas the flounder and other types of flatfish are able to match not just the color but also the silty or mottled sandy texture of the ocean floor beneath them.

C Most animals, though, cannot change their appearance so easily. Because background matching works only for a specific setting and often requires animals to remain motionless for long periods, a somewhat more effective strategy involves having a camouflage that works on many backgrounds, blending in with all, but not perfectly matching any of them.

D Disruptive coloration uses a pattern such as stripes or spots to disrupt the body outline. The pattern breaks up the contour of the animal’ body, confusing observers and making it difficult to distinguish an individual shape. Colors with more contrast, like a tiger’s stripes, tend to increase the disruptive effect. This type of camouflage works well for animals that travel in herds. It helps zebras blend In not so much with their background as with each other. Their major predator, the lion, sees a mass of moving stripes and has trouble targeting a specific animal. A single zebra, on the other hand, may use background matching when hiding in tall grass, where it’s black and white stripes merge with the green and yellow stalks. The different colors of the grasses and zebras are no help to a lion, which is color-blind.

E Animals with counter-shading typically have a dark backside and a light belly, which affect an onlooker’s perception of their three-dimensional appearance and help decrease their visibility in sunlight. Counter-shading also can create a more uniformly dark appearance, presenting an apparent lack of depth. Caterpillars make good use of this effect, which gives them a flat look that blends In with tree bark.

F Counter-shading is useful to birds and marine animals that are typically seen against a light environment from below and against dark surroundings from above. Predatory birds like hawks take advantage of it to conceal themselves from the small birds and rodents they hunt. While In fight, a dark back absorbs the sunlight above them and the light underside reflects the light below, diminishing telltale shadows that might give them away. On the ground or in a tree, their mottled brown feathers blend in with branches and leaves. Penguins also use counter-shading. Their white chests and black backs stand out on land but disappear in water where penguins spend most of their time. They are almost invisible to an observer looking down into dark water, while a creature In deeper water looking up sees a splash of white that looks like a beam of sunlight.

G Mimicry, or masquerading, works not by hiding a creature but by making it appear to be something else. Walking stick insects are virtually indistinguishable from twigs, and katydids look so much like green leaves that leaf-eating insects have been observed trying to chew on them.

H A type of mimicry known as aposematism involves masquerading as an animal that is undesirable or even dangerous. Predators bypass the foul-tasting monarch butterfly, but they also avoid the tasty lookalike viceroy butterfly. Coral snake impersonators, like the harmless scarlet snake, have the same red, black, and yellow bands but in a different order: black, yellow, red, yellow on the coral snake and red, black, yellow, black on the scarlet snake. Different types of moths use aposematism to scare off predators; some species have a big spot on each wing to mimic the eyes of large animal, while the hawk moth caterpillar has a pattern on its rear that looks like a snake head.

I Some predators use what is known as aggressive mimicry to disguise themselves as something harmless so they can catch prey off guard. Small animals are not afraid of turkey vultures, which are scavengers, not predators. So when the similar zone-tailed hawk flies with a group of turkey vultures, it has an easy time locating and zeroing on its living prey.

J No single type of camouflage works best in all situations, and many animals use more than one technique to enhance their ability to avoid detection by predators and prey alike.
