Upon completion of this course, the student will be able to:
1. Describe the features of the class mammalia and compare and contrast
the characteristics of the orders and families of marine mammals
within the class.
2. Summarize the key features of the marine environment and assess how
these features impact marine mammals and their predators and prey,
including concepts of population ecology and biogeography.
3. Compare and contrast primary and secondary production levels in major
areas of the ocean and explain how this impacts the distribution,
population size, and migration patterns of marine mammals.
4. Demonstrate an understanding of classification and systematics and
apply these concepts to marine mammals.
5. Synthesize the concepts of mechanisms of evolution, adaptation, and
speciation, and apply these concepts to marine mammal evolution.
6. Explain mammalian homeostasis and energetics and the anatomical,
physiological, and behavioral adaptations made by marine mammals for
life in the sea.
7. Compare and contrast capabilities and functions of the sensory systems
(sight, smell, touch, taste, and sound), for different marine mammal
groups and their use in communication, social organization,
orientation, and feeding.
8. Compare and contrast the various feeding mechanisms of marine mammals
and analyze how these differences impact upon, and are impacted by,
the social structure and physiological and morphological adaptations
of marine mammals.
9. Compare and contrast the mating and social systems of the different
types of marine mammals and analyze the role of habitat and evolution
in shaping these systems.
10. Summarize past and present threats to marine mammal populations
including hunting, pollution, habitat and prey loss and describe and
analyze the effectiveness of current national and international laws
regulating marine mammal populations.
11. Recognize and describe the marine mammal species found along the
California coast and describe their ecology, natural history, and
world population status.
