platyhelminth

A member of the phylum of flatworms that includes flukes, TAPEWORMS, and schistosomes. See LIVER FLUKE and SCHISTOSOMIASIS.

platyhelminth

or

flatworm

any invertebrate of the phylum Platyhelminthes, containing the TAPEWORMS (Cestoda), FLUKES (Trematoda) and planarians (Turbellaria). The Turbellaria are free-living flatworms which are aquatic and inhabit moist places on land. The two other groups are parasitic. They possess only an anterior opening to the gut system, there is no blood system and the animals show BILATERAL SYMMETRY. A mesoderm is present but there is no COELOM.

platyhelminth

one of the Platyhelminthes; the flatworms. Includes cestodes and trematodes, the tapeworms and the flukes.

Terrestrial mollusks, arthropods, and vertebrates are tolerant of desiccation and therefore are more fully terrestrial than are cryptozoic taxa such as platyhelminths, nemerteans, annelids, and onychophorans (Little 1983).
Platyhelminths, primarily represented by Digenea (flukes), were the most prevalent helminths found.
Molluscs belong to the superphylum Lophotrochozoa that also includes annelids, platyhelminths, and a range of other phyla members (Graham 2000).

Originally identified in mammalian tissues, NO has been identified in the signaling cascades of many invertebrates such as coelenterates, platyhelminths, nematodes, annelids, molluscs, arthropods, echinoderms, and urochordates (Martinez, 1995; Midler, 1997).
A good example is the mariner which, by being functional in both germ lines and somatic cell lines, could infect many organisms, crossing several phyletic borders (arthropods, platyhelminths, nematodes, chordates), probably by splicing into viral or other pathogenic genomes.
