Studying mammals: The opportunists
Many mammals are food specialists, with complex adaptations that gear them toward a particular food source. So how do the omnivores survive and prosper without these fancy evolutionary features? This free course, Studying mammals: The opportunists, examines the physiology, diet and strategies of some of these opportunistic feeders. It is the sixth course in the Studying mammals series.
