Yes.
"Manatees inhabit the shallow, marshy coastal areas and rivers of the Caribbean Sea and the Gulf of Mexico, . . . the Amazon Basin, . . . and West Africa. They frequently migrate through brackish water estuaries to freshwater springs. Florida manatees can move freely between salinity extremes, . . . [although] Studies suggest Florida manatees must have some access to fresh water for proper regulation of water and salts within their bodies.
The freshwater Amazonian manatee inhabits the Amazon River and its tributaries, and never ventures into salt water."
