Manatees and Dugong Sirenians are the only herbivorous marine mammals; feed on aquatic plants and algae Some species live in fresh and/or brackish water Inhabit temperate or subtropical waters Severely threatened by motor boat collisions, harmful algal blooms, pollution, and severe winters

Stellar’s Sea Cow (the sirenian you’ll never see) The Stellar Sea Cow was a large, herbivorous marine mammal formerly abundant in the North Pacific Described by naturalist Wilheim Stellar in 1741; hunted to extinction within 27 years of discovery! 8 meters long Fed on kelp Did otter hunting play a role?
