Explore the fascinating underwater realm and examine diverse marine ecosystems, ranging from ocean depths to coastal areas and estuaries, spanning tropical to polar regions. During your Bachelor of Science in Marine Biology, you'll develop a comprehensive knowledge of marine organisms, from microscopic cells and algae to invertebrates, fish, and marine mammals. Benefit from instruction by leading experts as you explore subjects like marine molecular ecology, microbiology, and the behavior, biology, and evolution of sea life. You'll learn and apply advanced techniques for collecting and analyzing data from marine environments and their inhabitants. St Andrews' coastal position along the North Sea provides the perfect setting for observing marine wildlife in its natural surroundings. The program combines laboratory work with hands-on fieldwork. The School of Biology houses the prestigious Scottish Oceans Institute, home to the internationally recognized Sea Mammal Research Unit (SMRU). Students can engage with SOI and SMRU researchers through small-group sessions, practical exercises, research initiatives, and community events at the institute.
