Elephantiasis occurs in the presence of microscopic, thread-like parasitic worms such as Wuchereria bancrofti (the most common), Brugia malayi, and Brugia timori (also known as B. timori), all of which are transmitted by bites from infected mosquitoes.Infections usually begin when people are children.he worms are spread by the bites of infected mosquitos. Infections usually begin when people are children. There are three types of worms that cause the disease: Wuchereria bancrofti, Brugia malayi, and Brugia timori.
An analogous structure is a structure that has a similar function but different components. For example, the wings of a butterfly verses those of a bird. In both cases, the fu â¦ nction is flight, but the wings are build differently.
Examples of analogous structures range from wings in flying animals like bats, birds, and insects, to fins in animals like penguins and fish. Plants and other organisms can also demonstrate analogous structures, such as sweet potatoes and potatoes, which have the same function of food storage.pecies may also have similar traits even though they are not related to each other. This usually results because the species live in similar environments and fill similar ecological roles. The structures in this case are known as analogous structures.
