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. The eye of a human is very similar in structure to the eye of the octopus. In fact, the octopus eye is superior to the human eye in that it does not have a blind spot.Structurally, that is really the only difference between the eyes.nalogous structures do not have to have the same evolutionary path. One analogous structure may have come into existence long ago, while the analogous match on another species may be relatively new.
