This semester course may be taken on its own or as a predecessor to Vertebrate Zoology. Invertebrate Zoology will introduce students to the phylogenetic relationships between and distinctive features of invertebrate phyla, including poriferans, cnidarians, platyhelminthes, nematodes, molluscs, annelids, arthropods, and echinoderms. Important concepts in invertebrate body plans will be explored, including symmetry, cephalization, body cavity, gut formation, and segmentation. Biological processes of invertebrates including locomotion, body support, reproduction, embryonic development, feeding, digestion, osmoregulation, excretion, circulation, respiration, sensory function, and behavior will be addressed as well. Frequent laboratory exercises, including traditional dissection, studies of development, and behavioral observations, will be integral to the learning experience. Short and long-term projects, laboratory exercises, homework, quizzes, and tests provide multiple opportunities for students to demonstrate their understanding of complex biological concepts.
