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.
Analogies are anatomical features that have the same form or function in different species that have no known common ancestor. For instance, the wings of a bird and a butterfly are analogous structures because they are superficially similar in shape and function.Both of these very distinct species lines solved the problem of getting off of the ground in essentially the same way. However, their wings are quite different on the inside.or instance, the wings of a bird and a butterfly are analogous structures because they are superficially similar in shape and function.
