The course covers the biology of marine life, with emphasis on the roles that marine plants and animals play in their environment and the structural and physiological adaptations necessary to fulfill those roles. It is divided in four parts: The first part introduces students to marine biology and the basic sciences that underpin it. The second part surveys the diversity of marine life from the perspective of ‘organismal’ biology. It emphasizes functional morphology, ecological and physiological adaptations, and economic importance and other significance to humans. The third part takes the students in virtual tours into the world oceans, starting with an introduction to some fundamental principles of marine ecology. The fourth part discusses various ways in which humans interact with the world oceans (i.e. uses of marine resources, impacts on marine environment) and the influence of the ocean on human experiences.
