<p><span>Per- and polyfluoroalkyl substances (PFAS) are ubiquitous, synthetic anthropogenic chemicals known to infiltrate and persist in biological systems as a result of their stability and bioaccumulation potential. This study investigated 15 PFAS, including short-chain carboxylic and sulfonic acids, and their presence in a threatened herbivore, the West Indian manatee (</span><span><i>Trichechus manatus</i></span><span>). Seven of the 15 PFAS examined were detected in manatee plasma. Perfluorooctanesulfonic acid (PFOS) (ranging from 0.13 to 166 ng/g ww) and perfluorononanoic acid (PFNA) (ranging from 0.038 to 3.52 ng/g ww) were detected in every manatee plasma sample examined (</span><i>n</i><span> = 69), with differing medians across sampling sites in Florida, Crystal River (</span><i>n</i><span> = 39), Brevard County (</span><i>n</i><span> = 18), Everglades National Park (</span><i>n</i><span> = 8), and four samples (</span><i>n</i><span> = 4) from Puerto Rico. With an herbivorous diet and long life-span, the manatee provides a new perspective to monitoring PFAS contamination.</span></p>
