Distribution Occurs essentially annually along the coast of NC, mainly along the southern third of the coast (Carteret County southward). Manatees tend to be seen inshore of the ocean, such as along the Intracoastal Waterway or other bays, estuaries, and lower portions of large rivers (at bay mouths), sparingly upriver as far as eastern Pitt County (Tar/Pamlico River), New Bern (Neuse River), and Bladen County (Cape Fear River). It has occurred also along the entire NC coast (including Currituck County), again typically seen inward of the ocean itself.

Occurs in warm waters along the Atlantic coast, sparingly as far north as the Chesapeake Bay area, but mainly from FL southward.
Abundance Rare but essentially annual along the southern coast, with a few sightings in a given year. More frequent the farther south along the coast; not seen annually north of Cape Hatteras (where best considered very rare).
Seasonal Occurrence Almost always in the warmer months of the year, as a visitor/stray northward from FL and other tropical waters.
Habitat In NC, favors brackish waters of estuaries, bays, and large river mouths; probably does much migration up and down the Intracoastal Waterway. Less frequently seen in the inshore ocean. Seldom or never seen up-river farther than the embayed partions, such as New Bern.
Behavior This is a very tame and sluggish mammal, not afraid of swimmers or scuba divers. A moderate number are killed by speeding boats, farther southward.
Comments The species is also called the Florida Manatee. It was formerly listed as Endangered by the U.S. Fish and Wildlife Service, but in recent years (2017) has been downlisted to Threatened at the Federal (and thus also the State) level. However, there have been massive and very concerning numbers of fatalities in FL in the past few years, making this downlisting to Threatened perhaps premature or "hasty".
