Marine Biology is the study of ocean life. As you might expect, life in salt water is vastly different from life in a terrestrial or freshwater environment due to factors like salinity, water circulation, and atmospheric pressure. How, for example, can organisms living in salt water avoid dehydration? How do organisms living in the depths of the ocean handle the immense pressure? How do the environmental factors in marine communities affect biodiversity? How do some animals manage to alternate between the demands of terrestrial life and the demands of marine life? In this course, you will learn the answers to these questions and more. This course will touch on a number of different subfields of biological study (including biochemistry, physiology, zoology, botany, and ecology) within the context of the ocean environment.
