Of the 20 major animal phyla, 19 consist of invertebrates, including many familiar animals such as insects and snails, and more unusual ones including vampire squids and sea cucumbers. This course examines the “the small things that matter” in the context of their evolution and systematics. It looks at the origin of life in the sea and the enormous diversification following terrestrialisation. The focus is on major radiations and key evolutionary innovations including the transition from radial to bilateral symmetry and the development of a mesoderm and complex organs, that have occurred in the transition from simple to complex organisms. A 3 day field trip will give students a solid grounding in the marine and terrestrial invertebrate fauna of south-eastern Australia and the microhabitats they occupy. The practical component of the course will teach students techniques of specimen preservation and the use of biological keys in species identification.
Upon successful completion, students will have the knowledge and skills to:
- Understand and communicate the major evolutionary innovations in invertebrate groups, and describe the functional significance of associated morphologies and behaviours.
- Analyse invertebrates in laboratory and field conditions, and use taxonomic keys for identification.
- Understand the requirements for collection and short-term maintenance of invertebrate species for photographic and scientific observation.
- Interpret formal taxonomic descriptions and understand principles of taxonomic precedence, synonymy, revision, and type specimen designation.
- Construct phylogenies by hand from suites of taxonomic characters, and critically evaluate groupings on the basis of monophyly and the principles of phylogenetic systematics.
Field Trip: The cost of the fieldtrip in Kioloa will be around $200

The ANU uses Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. While the use of Turnitin is not mandatory, the ANU highly recommends Turnitin is used by both teaching staff and students. For additional information regarding Turnitin please visit the ANU Online website.
Workload60 contact hours, 50 non-contact hours. Plus a weekend field trip to Kioloa during March.
