These are mostly endoparasites found in animals including human beings. Flatworms are bilaterally symmetrical, triploblastic and acoelomate animals with organlevel of organisation. Hooks and suckers are present in the parasitic forms. Some of them absorb nutrients from the host directly through their body surface. Specialized cells called flame cells help in osmoregulation and excretion. Sexes are notseparate. Fertilisation is internal and development is through many larval stages. Some members like Planaria possess high regeneration capacity.

Taenia (Tapeworm) and Fasciola (liver fluke) are examples of parasitic platyhelminthes. Peculiar features in parasitic platyhelminthes are as follows. 1. They have dorsiventrally flattened body and bear hooks and suckers to get attached inside the body of the host. 2. Their body is covered with thick tegument, which protects them from the action of digestive juices of the host. 3. The tegument also helps in absorbing nutrients from the host’s body.

It protects the animal from the action of digestive enzymes of the host. 2. The body of platyhelminthes is dorsoventrally flattened. 3. Platyhelminthes possess adhesive structures such as suckers and hookers that are helpful in deriving nutrition from the host body 4. Locomotory organs are absent 5. The reproductive system is well developed. Mostly they are hermaphrodite.

flatworm, also called platyhelminth, any of the phylum Platyhelminthes, a group of soft-bodied, usually much flattened invertebrates. A number of flatworm species are free-living, but about 80 percent of all flatworms are parasitic—i.e., living on or in another organism and securing nourishment from it. They are bilaterally symmetrical (i.e., the right and left sides are similar) and lack specialized respiratory, skeletal, and circulatory systems; no body cavity (coelom) is present. The body is not segmented; spongy The phylum consists of four classes: Trematoda ( General features Importance Although some platyhelminths (flatworms) are free-living and nondestructive, many other species (particularly the flukes and tapeworms) parasitize humans, domestic animals, or both. In Europe, Australia, and North and South America, Diphyllobothrium latum); in parts of the southern Hymenolepis nana). In Europe and the United States the beef tapeworm ( Taenia saginata) is common because of the habit of eating undercooked steaks or other beef products. Parasites in immature stages (larvae) can cause serious damage to the host. A larval stage of the gid parasite of Multiceps multiceps) usually lodges in the sheep Echinococcus may occur almost anywhere in the body of sheep.
