The Loa loa worm, better known as the "eye worm," which inhabits the rainforests and swamps of West Africa , infects humans through the bite of a deer fly or mango fly. The female worm can be between 4 and 7 cm long and 0.5 mm in diameter; the male is smaller.
Eyeworms roam under the skin of their victims at all times, feeding on the fluids of human tissues, moving through the bloodstream. Occasionally they can reach the eyes and are quite painful.
Other equally terrifying parasites include : the dragon worm, the animal-eating worm, the head-opening parasite, the crab castrating barnacle, the tongue-eating parasite, the Australian paralysis tick, the skin-penetrating parasite, the spider handler wasps or the parasite that controls the mind.
