Morphology, taxonomy, natural history and phylogeny of invertebrate animals, with emphasis on biodiversity; class includes both lecture and lab. Labs include study of preserved material and demonstration of living animals in aquaria and terraria. Prerequisite: BIOL 214 or approval of instructor.
Prerequisites, be able to:
1. Classify organisms using the Linnean system (kingdom, phylum, class, order, genus, species)
2. Describe the characteristics of large animal phyla: Porifera, Cnidaria, Annelida, Mollusca, Arthropoda, Echinodermata, Chordata
3. Describe the basic animal systems: nervous, digestive, reproductive, excretory, skeleto-muscular, respiratory, circulatory, endocrine
4. Compare and contrast mitosis and meiosis
5. Describe the transitions in early embryonic development from fertilization to juvenile
6. Explain the differences between prokaryotes and eukaryotes, protists and Animalia
7. Explain why oxygen and water are essential for living organisms
8. Explain what an energy budget is
Learning outcomes, be able to:
1. Identify major groups of non-photosynthetic protists, know their habitats and which ones pose threats to human health
2. Explain how sponges differ from all other multicellular animals
3. Describe the features that enable cnidarians and other invertebrates to survive largely by diffusion
4. Identify embryonic germ layers, explain how they differ between phyla, and know why animals with mosaic development are particularly useful in studying cellular development
5. Compare/contrast the nervous systems of a medusa, flatworm, annelid, cephalopod, ancient versus derived arthropod, echinoderm, and vertebrate
6. Explain how colonies are derived and how they feed and reproduce, including differentiated individuals
7. Define parthenogenesis, describe the ecological situations in which it is likely to occur, and name animal groups in which it occurs
8. Describe the life cycles of common nematode and flatworm parasites
9. Describe the enormous diversity among the annelids, mollusks and arthropods, and give reasons for their success in so many habitats
10. Describe suspension, deposit, and indirect deposit feeding, and give examples of animals that use each strategy.
11. Explain which features (genetic, embryological, and anatomical) link the echinoderms, hemichordates, and chordates.
12. Describe the structure and function of the unique water-vascular system of echinoderms
13. Compare the non-vertebrate chordates in regard to their modes of feeding, motility, early development, and habitat
14. List common invertebrates that are important in ecosystem dynamics, as seafood, as pests, or as experimental subjects
15. List descriptive information for all of the animal phyla, especially those that occur in Texas and the Gulf of Mexico.
