Choosing a Parasite: Just like all other creatures, parasites have evolved specializations to allow them to survive in their own specific niches. These specializations have created a wonderous variety. Worms which swim through the blood; small protozoa which eat the brain, and all sorts of creatures in between. Each of these creatures has specialized into their own niche. This page is an exercize to explore why and how these various creatures have evolved.
