You must know all of the structures and terminology listed below. Be sure to use high magnification when necessary to see detail, and always note magnification next to each drawing. Lebel the structures the are listed with each organism and answer all of the questions. Add arrows, circles, etc. to the pictures if directed to label structures. If unable, describe the structures and their location next to the picture. Kingdom Animalia 1 2 • • Phylum Porifera  Examine the following members of the phylum Porifera (sponges). Draw each specimen, describing morphology and labeling all appropriate parts. What type of symmetry is characteristic of this phylum? 1. Assorted sponges (preserved, whole mount) Note: incurrent pores, incurrent canals, central cavity (spongocoel), and osculum. 2. Grantia (preserved, whole mount) Observe under a dissecting microscope. Label incurrent pores, osculum. 3. Grantia – cross section (prepared slide) Label incurrent canals and choanocytes (collar cells). Phylum Cnidaria 3 • • • • • -Examine the following members of the phylum Cnidaria (cnidarians). Draw the indicated specimens, describing morphology and labeling all appropriate parts. Question 1: What type of symmetry is characteristic of this phylum?  Class Anthozoa (corals and sea anemones) 4. Sea anemone (preserved, whole mount) Label oral disc, basal (pedal) disc, mouth, column, and tentacles. Question 2: Is this an example of the polyp or medusa body form?  Class Hydrozoa (hydrozoans) 5. Hydra – budding (live specimen, and prepared slide) Prepare a slide of the live specimen. In three or four sentences, describe the movement of a living Hydra. Question 3: Is this an example of the polyp or medusa body form? Label mouth, tentacles, body column, basal (pedal) disc, and buds in both the live and prepared slide specimens. Budding represents asexual reproduction in Hydra. 6. Obelia – hydroid colony (prepared slide) Question 4: Is this an example of the polyp or medusa body form?  Class Scyphozoa (jellyfish) 7. Aurelia (preserved, whole mount) ▪ Label the bell, tentacles, and gonads. Phylum Ctenophora  Observe the following member of the phylum Ctenophora (ctenophores or comb jellies). Describe morphology and label the ctenes (combs). 8. Ctenophore (preserved, whole mount) Question 5: How do ctenophores differ from cnidarians? Phylum Platyhelminthes  Examine the following members of the phylum Platyhelminthes (flatworms). Describe morphology and label all appropriate parts. Question 6: What type of symmetry first appears in the Platyhelminthes? 9. Planarian – (Live specimen, and prepared slide) Label auricles, eyespots, mouth. 10. Taenia – anterior region (prepared slide) Label scolex, hooks, suckers, and proglottids. Taenia is a parasitic tapeworm. Question 7: What is the purpose of the hooks and suckers on the scolex? Phylum Rotifera  Observe the following member of the phylum Rotifera (rotifers). Describe morphology and label all appropriate parts. 11. Rotifer (live specimens) Label corona, stomach, intestine, foot, and toes. Describe the locomotion of living rotifers. Phylum Annelida -Examine the following members of the phylum Annelida (annelids). Describe morphology and labeling all appropriate parts. Question 8: What major morphological feature first appeared in annelids?  Class Polychaeta (polychaetes) 12. Nereis – head region (preserved, whole mount) ▪ Identify the segmentation, parapodia, mouth, and prostomial cirri Phylum Nematoda 4  Observe the following member of the phylum Nematoda (roundworms). Describe morphology and identify the male and the female and what the difference is. 13.
