These specialized systems are exemplified by the Planaria which is a heterotrophic free-living flatworm. There are three Classes of flatworms. Class Turbellaria – example Planaria - free living, incomplete gut, no suckers or hooks. Class Trematoda – example flukes - parasitic, incomplete gut, _____ _____. Class Cestodae – example tapeworms -
Like all flatworms, planaria belong to the Kingdom Animalia, and the Phylum Platyhelminthes. This phylum also contains parasitic flatworms, like the tapeworm and the liver fluke. Free-living flatworms like the planaria are grouped into the Class Turbellaria. The most common species studied in the lab is the brown planaria, Dugesia.

. . The simplest animals that are bilaterally symmetrical and triploblastic (composed of three fundamental cell layers) are the Platyhelminthes, the flatworms. The flukes (Trematoda) are a class of parasitic worms belonging to the phylum Platyhelminthes. One species, Leucochloridium macrostomum, Flukes parasitize members of all vertebrate classes but most commonly parasitize fish, frogs, and turtles; they also parasitize humans, domestic animals, and invertebrates such as mollusks and crustaceans.

Tapeworms. Tapeworms (Cestoda) are a highly diversified group of ubiquitous endoparasites that generally have a two-phase life cycle: vertebrates serve as final hosts and all orders may utilize arthropods, other invertebrates or even vertebrates as first intermediate hosts with the sole exception of the Caryophyllidea, whose eggs only infect oligocheate annelids.

2019-12-24 · Planarians and tapeworms are two types of flatworms that belong to phylum Platyhelminthes. Planarians are unsegmented flatworms, which are free living. They belong to class turbellaria. On the other hand, tapeworms are segmented flatworms which are parasitic and live in the intestines of animals. They belong to class Cestoda. Platyhelminthes are mostly worm-like creatures that are dorsoventrally flattened, meaning they look like a ribbon. This is why they are called names such as Tapeworm, Flatworm, Fluke and Planarian.
