Despite ongoing conservation efforts, Manatees, such as this one from Crystal River Water, Florida, continue to be endangered due to polluted waterways and boat strikes. This image is one of five photographs selected by the public to appear in “Portraits of Planet Ocean: The Photography of Brian Skerry,” which opens Sept. 17, 2013 at the Smithsonian's National Museum of Natural History in Washington, D.C. in celebration of the fifth anniversary of the Sant Ocean Hall.
