Marine invertebrates are members of every known animal phylum, and Barkley Sound contains a fantastic diversity of them. In this course, students investigate the zoology of living marine invertebrates: their functional morphology, behaviour, ecology, and phylogenetic relationships. On a tidal schedule, we will conduct inspiring – and intensive – field work to explore a variety of habitats including exposed rocky shores, mudflats, eelgrass beds, and beaches, and to collect a tremendous range of organisms, from Asteriidae to Zoantharia, and everything in between. We will also spend exhilarating – and extensive – time in the lab examining the animals up close and investigating their comparative morphology and behaviour. Field and lab work will be complemented by activities, discussion, lectures, and independent research.
