Intrasomatic differentiation in Placozoa. The main difference between the Placula and Trichoplax is the presence of (a) a third somatic cell type in the feeding epithelium, the gland cells, and (b) a fourth somatic cell type sandwiched in between the two epithelia, the so-called fiber cells. The latter are loosely connected to each other, tetraploid, contractile and capable of stimulus.
The most basal animals, the Porifera, Ctenophora, Cnidaria, and Placozoa, have body plans that lack bilateral symmetry. Their relationships are still disputed; the sister group to all other animals could be the Porifera or the Ctenophora, both of which lack hox genes, important in body plan development.

both for my anatomy of invertebrates, and for the insect morphology courses. True, we had Libbie H. Hyman's 6 volume (incomplete) work of the anat- omy of some phyla of invertebrates, but she never got to the insects. Until this year, insect morphol- ogy texts were restricted mainly to the gross as- pects, mostly external, of insect structure. Members of the phylum Cnidaria include hydras, jellyfish, sea corals, and sea anemones. Cnidarians live primarily in marine environments. They have tissue organization and a body plan displaying radial symmetry; that is, the organisms are circular with structures that radiate outward. The ends of the structures have tentacles with stinging devices called cnidocyte that help in defense and in.

The Ctenophora were seen as the most probable sister group of the Cnidaria. Arguments for the monophyly of the cnidarian classes Anthozoa, Scyphoza, Cubozoa, and Hydrozoa were : Stanley Shostak. The text-book depiction of the typical cnidarian life cycle is an alternation between a medusa and a polyp (termed metagenesis), the former the sexually reproductive stage and the latter the asexual stage.

Here is the newest self-contained, three-part volume in the award winning Microscopic Anatomy of Invertebrates (MAI) series. It covers the basic physiology of Chelicerate Arthropodia, a diverse class of invertebrates that includes mites, ticks, spiders, scorpions and related forms.
Abstract. Cnidarians display most of the characters considered as milestones of metazoan evolution. Whereas a tissue-level organization was probably already present in the multicellular common ancestor of all animals, the Urmetazoa, the emergence of important animal features such as bilateral symmetry, triploblasty, a polarized nervous system, sense organs (eyes, statocysts), and a (chitinous Cited by: characterized by having 1) a gastrovascular cavity which only has one opening and 2) stinging cells called cnidocytes (figure 3).
Cnidocytes contain microscopic structures called nematocysts, which are coiled threads that Cnidaria be discharged like tiny harpoons. Two body plans are seen in this phylum; the sessile polyp and the free-swimming medusa. Microscopic anatomy of invertebrates.

Wiley-Liss, New Y ork, pp 13– Guidi L. Four phyla (Placozoa, Porifera, Cnidaria, and Ctenophora) are typically thought to have an ancient origin within Metazoa.
The dicyemid mesozoans, once hypothesized to be non-bilaterian metazoans, have since been shown to possess central class Hox genes indicating that these enigmatic parasites are secondarily simplified bilaterians (Kobayashi. The enigmatic animal phylum Placozoa holds a key position in the metazoan Tree of Life.
A simple bauplan makes it appear to be the most basal metazoan known and genetic evidence also points to a position close to the last common metazoan ancestor. Trichoplax adhaerens is the only formally described species in the phylum to date, making the Placozoa the only monotypic phylum in.
