Anthropoda

Phylum Annelida, also known as segmented worms, are so called because of their body segments. As seen in this picture, they are divided into many parts. Each segment has its own nerve cells, although the stomach and certain nerve cells pass freely through all of them. The segmentation allows for flexibility and structure. This structure is like the human body's spine, which is composed of many bones segmented. Its body has repeating organs which is characteristic for its species. In this species is a class most people know all too well, which is leeches. Its the type that is most generally associated with parasitism. The problem is that these parasites can also transfer other parasites while feeding, which is why they are dangerous.

Acanthocephala, while not as readily found in most animals as other parasites, are nevertheless found in many animals, quite like all parasites. Also called throny-headed worms, they are so called because of a proboscis which is usually covered in many hooks. It takes nutrition in from the skin, absorbing it instead of digesting it with the mouth. One parasite of this order is very clever, namely Polymorphus minutus, in that it changes the color of the shrimp it infects to the color blue. Scientists have tested that blue shrimp are more likely to be taken by birds then the uninfected ones. This is done so that the parasite can then infect the bird, its main host. Thus, that is how one parasite has adapted after time.

Anthropoda are, basically, the insects you see everyday. These are the parasites that you see most of the time, but do not notice, although some are a sign that you should notice. Some parasites include the American cockroach, bedbugs, fleas, lice and others. Most of these animals are not that dangerous, although the problem is not that, but the number of diseases they carry. An example is the lice, which is a transmitter for typhus, a disease which is transmitted by the lice bites. Another example are cockroaches, which transmit many protozoan cysts, where parasitic protozoa can infect your body and cause pain and disease.
