First discovered in 1900, lowly was known about the happy-face spider until 1972. The obviously named happy-face spider is a gnomish spider found in the native rainforests of the islands Maui, The Big Island of Hawaii, Oahu and Molokai at elevations of universal gravitational constant to 6000 feet. Typically around a quarter of an inch long, its diet consists of small(a) insects that it hunts mainly during the night for small insects. They spin their webs on the undersides of leaves of specific plants and usually avoid contact with humans or some other potentially risk of infection animals, although only birds present a natural threat. Humans present a possible danger due to loss of habitat to agriculture, but the universe of discourse is apparently healthy. The happy-face spiders most admired feature is its splendid yellow people of coloring and a strange pattern of red and forbidding spots on the abdomen. These spots vary widely from spider to spider, tell on them of interest to scientists who have hypothesized that the different spots provide camouflage against birds and other predators. Strangely enough, the red and black spots, combined with the yellow body, tend to make the spiders abdomen look like the widely known yellow smiley face. The expressions on the abdomen of the spider can range from sad, happy, and excited, to bored or angry.though individuals differ extremely in their color patterns, these differences are evenly distributed, with the selfsame(prenominal) ratio of Yellow forms to Red front forms in every population, disregarding of its separation from the others. Mating experiments reveal that the genetic mechanism for achieving these similar color morphs is different on each island. Results for the Maui spiders reveal a more truthful system of genetic control where the individual, regardless of sex, will be aslant according to a single gene. On Hawaii, however, it is apparent that two genes ensure the color morph, with pair s of color forms restricted to one sex or the other.
