The most common trematode is the liver fluke fasciola hepatica. Fig: diagram of liver fluke. 4.4.2 Life cycle of fasciola Hepatica (Liver Fluke) The adult lives in the bile duct of its primary host. This could be sheep, goat, cattle and occasionally humans. The adult lays egg which passes out in the host feces.
Cestodes (tapeworms) and trematodes (flukes) have complex life-cycles, with mature Two planarian species have been used successfully in the Philippines, Hence the traditional sub-phylum "Turbellaria" is paraphyletic, sin
Cestoda, Trematoda are parasitic while Turbellaria contains free-living worms. They are acoelomates and have no specialized circulatory and respiratory organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. Planaria, liver fluke, and Taenia all are flat worms. The phylum name Platyhelminthes literally means "flatworms." Members of this phylum are soft, thin-bodied, leaf or ribbonlike worms, including the familiar planaria of ponds and streams, as well as the flukes and tapeworms parasitic in human and other animal bodies. Flatworms belong to the phylum Platyhelminthes, which includes planarians, flukes, and tapeworms. Learn more about these animals as you explore the contents of this lesson.
Second, they have bilateral symmetry. In other words, they have a left and right half. Next, these worms have tissues that are organs. Introduction to the Platyhelminthes Life in two dimensions. .
So, animals of this phylla are triploblastic. Examples. Dugesia (planaria) is free living, Fasciola (liver fluke) and Taenia solium (tape worm) are parasitic animals.
These organisms may live on the outside of the host (ectoparasites) or within the host (endoparasites). Tapeworms seem to specialize in the gut tracts of many kinds of vertebrates, while flukes are found in the blood stream or organs associated with the blood, like the liver.
Phylum: Platyhelminthes (Flatworms)
They have thick body covering, which protects them from host body. 2. Planaria- has eyes, auricle, class Turbellaria, lives in fresh water Clonorchis- class Trematoda, parasitic, lives in animal/people Similar- hermaphroditic, phylum Platyhelminthes, gastro-vascular cavity, nerve ladder, flame cells, reproduces sexually & asexually triploblastic 4. Ectoderm- skin and nervous system Endoderm- lining of digestive Tapeworm, liver fluke, and planaria are all Platyhelminths and they have a flat body without any ridges or grooves.
These animals belong to the phylum . Annelida. Members of this phylum may be most familiar: the common earthworm, leech and nightcrawler belong to this group. There are three general types of segmented worms.
