Annelids: I learned that the phylum Annelids can consist of many creatures such as earthworms, leeches, and scale worms can adapt to a variety of environments. Annelids’ bodies are divided into segments which are seen as rings by the naked eye. They have muscles which help them move by contracting their longitudinal and circular muscles. When Annelids take in food, the food particles travel through one end of the body and are excreted out the other side. The video enhanced my understanding about
Taxonomic Classification Paragonimus westermani (P. westermani) is part of the phylum Platyhelminthes. Platyhelminthes are flatworms, and are characterized by being acoelomate, triploblastic, and having a simple bilateral symmetry (Berkley.edu). The P. westermani is a member of the Trematoda class. Trematodas are flukes (parasite flatworms) that live inside vertebrates as their primary hosts and inside mollusks as intermediate hosts (wikipedia.org-trematoda). The parasite’s order is Plagiochiformes
As time progresses, animals have become bigger and display more of a complex body. In some cases, this is not always true. The Poriferas and Cnidarians do not have a difficult structure like the Platyhelminthes. The body structures can determine a lot about how these animals survive in their environment, and it is important that their structure can manage their distribution of gases, and obtain food and waste. These facts and information will show proof of the many characteristics and bodily functions
The history of taxonomy dates all the way back to the 4th century, where organisms were divided into 2 groups, plants and animals by a Greek philosopher, Aristotle. Early naturalists did not acknowledge that the similarities and differences between the two organisms were results of evolutionary means. So as the years went on, classification gradually changed and slowly became more and more sophisticated. In 1758, Carlos Linnaeus established the first major break through with classification, and
