Chapter 9 - The Acoelomate Animals

Extractions: CHAPTER 9 THE ACOELOMATE ANIMALS PHYLUM PLALYHELMINIHES TISSUE-ORGAN LEVEL OF ORGANIZATION THE ACOELOMATE PHYLA The acoelomate animals, or animals that have no body cavity, include the phylum Platyhelminthes (Gr., platys flat, helmins, worm) and the phylum Rhynchocoela (Gr., rhynchos, beak, +koilos, hollow). In acoelomate animals the space between the body wall and the digestive tract is not a cavity, as in higher animals, but is filled with mesenchyme ( parenchyma ) and muscles, both derived from mesoderm. The platyhelminths, or flatworms, are a large and economically important group because they include not only the free-living planarians but also the parasitic tapeworms and flukes . The rhynchocoels (formerly called Nemertina) are the ribbon worms , often called nemertine or nemertean worms. They are all marine and are characterized by an eversibl proboscis that can be thrown out with great speed to capture food.

Extractions: Partial 18S rRNA gene sequences of four macrodasyid and one chaetonotid gastrotrichs were obtained and compared with the available sequences of other gastrotrich species and representatives of various metazoan phyla. Contrary to the earlier molecular data, the gastrotrich sequences did not comprise a monophyletic group but formed two distinct clades, corresponding to the Macrodasyida and Chaetonotida, with the basal position occupied by the sequences of Tetranchyroderma sp. and

Extractions: Ch. 10 - Acoelomates - Miller and Harley I. Evolutionary perspective A. Phyla Platyhelminthes, Gastrotricha and Nemertea were the first to exhibit bilateral symmetry and more complex body organizations than Cnidarians. B. All these are triploblastic acoelomates C. Platyhelminthes - 1. flatworms 2. tapeworms 3. flukes D. Nemertea - small group of elongate, unsegmented soft bodied worms, mostly marine and freeliving E. Phylum Gastrotricha includes members that inhabit space between bottom sediments II. Phylum Platyhelminthes A. Characteristics: 2. Range in size from 1 mm to 25 m. 3. ectoderm becomes epidermis, endoderm becomes gv cavity 4. mesodermal tissues include parenchyma - filler tissue a. skeletal support b. nutrient storage c. motility d. reserves of regenerative cells e. transport of materials f.
