There are only five extant species in the mammalian order Sirenia. All of them are in danger of extinction, primarily from anthropogenic threats. This lecture reviewed the biology and natural history of these unique animals, discuss the variety of risks they face, and summarize the efforts to protect and conserve them. Keith focused on the ecological roles of manatees and dugongs and the probable ecosystem consequences of their demise. The philosophical rationale for protecting endangered species was also addressed.
