Film. In Process Record. Sean K. Todd. Originally produced by The Great Courses in 2018. Semi-aquatic marine mammals exhibit behaviors quite different than those who live fully in the water. In the former, an entire female community in one geographic area can come into estrus simultaneously and needs relatively few males to reproduce. In the latter, reproduction appears to be one of the driving forces of whale songs that can be heard over thousands of kilometers. Mode of access: World Wide Web. Technology. Biology.
