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.
The analogous features then help that species survive in the environment. One example of analogous structures is the wings of bats, flying insects, and birds. All three organisms use their wings to fly, but bats are actually mammals and not related to birds or flying insects. In fact, birds are more closely related to dinosaurs than they are to bats or flying insects.
