Summary Introduction
Introduction: The coelomate (main body cavity) phyla are divided into two distinct categories: Protostomes and Deuterostomes. The members of phylum annelida are considered as members of Lophotrochozoa (clade of the protostome animals) that also includes molluscs and

- compare cnidarians to sponges and to the clade containing flatworms, mollusks, and annelids. What features are similar among these groups? What features are different?arrow_forwardClass Gastropoda and Class Bivalvia independently evolved modifications to their body plan that allowed them to invade sandy and muddy habitats, burying their bodies under the surface and accessing the surface via siphons. For an example organism in each Class, (1) draw a diagram showing the morphological modifications and (2) write a description of how this organism had evolved from the hypothetical ancestral mollusk (HAM) body plan.arrow_forwardPhylum Arthropoda: 1. Comment on the size (number of species) within this phylum. 2. General Body Plan: (circle the appropriate answer) a) Simple or complex, b) Do they have true tissues? Yes or No c) asymmetry, radial symmetry, bilateral symmetry d) Do they have organs? Yes or No e) What type of appendages? f) What type of skeleton? 3. Describe molting.arrow_forward

We now know that: (1) Brachiopoda is more closely related to Mollusca; and (2) Bryozoa forms the sister-group to the clade formed by Brachiopoda+Mollusca. In the space below draw a phylogenetic tree showing the correct interrelationships among the 5 clades listed: Bryozoa: Brachiopoda: Linguliformea: Craniiformea: Rhynchonelliformea: Please include mollusca.

- Create a body plan table (Insert → Add Table) for the following animal phyla: Porifera, Cnidaria, Platyhelminthes, Mollusca, Annelida, Nematoda, Arthropoda, Echinodermata, and Chordata. Describe each phylum by identifying the following body plan features. Use Lesson 12 (Chapter 32) and Lesson 13 (Chapter 33) as a guide. 1) Symmetry: Asymmetrical, Radial, or Bilateral 2) Tissue type: Parazoa, Eumetazoa (diploblastic), or Eumetazoa (triploblastic) 3) Body cavity (if triploblastic): Acoelomate, Psuedocoelomate, or Coelomate 4) Developmental mode (if Coelomate): Protostome or Dueuterostome Note: Depending on the body plan, features 3 & 4 may not apply to specific phyla. * Please answer 3) and 4) ONLY.

Charles a Biology student in California has found at the beach an animal he cannot name. What are some of the questions that he should ask to help determine the phylum of the animal? Based on the data that you recorded during this lab do you see a relationship between symmetry, cephalization, and number of germ layers? Can you tell what germ layer appears last? Name three characteristics or features in the phyla studied that you could tell are ancestral or primitive and three that you may call advance? Explain further?arrow_forwardYou take a field trip to tide pools in Puget Sound and encounter all sorts of Animals.
