Extractions: Platyzoan animals Again this week there is a fair bit of material that we need to cover, especially since we're actually looking at a whole Infrakingdom The platyzoa. While initially these are the spiralian animals that didn't fall into the lophotrochozoa and ecdysozoa it's becoming clear that this may actually be a natural assemblage that's unified by being acoelomate triploblasts. Most prominant of the bunch are the Platyheliminthes and we'll spend most of our time in the lab looking at them. Last year you had a chance to examine Dugesia , and Chlonorchis and a tapeworm, this year we add a few more to round things out. Bdelloura is this years example of a turbellarian and you'll see a lot more of the internal features with this specimen than you did with Dugesia . We've also got the ectoparasitic monogenean and completely new trematodes for you to look at. We round out our look at the flatworms with our old friend the tapeworm. One of the reasons for the success of the phylum is that they have left the free living life and are now mostly parasites. We refer to Platyhelminthes as being preadapted for parasitism and you'll want to find as many examples of this in the specimens that you will be looking at. Other platyzoans are available either as live preps or prepared microscope slides. These include Gastrotrichs, Acanthocephala and Rotifers.
