Distribution Accidental in NC. Known only from a recent stranding in Carteret County.

A North Atlantic species, found west to Labrador and south to New England; occurs mainly over the Continental Shelf.
Abundance Though numerous and often common in the North Atlantic, with a range not dissimilar to that of the related Atlantic White-sided Dolphin, the White-beaked Dolphin does not occur or stray as far south -- especially as there are at least 10 strandings of Atlantic White-sided Dolphins in NC. Must be considered as an accidental stray in the state, though to be looked for in cold offshore waters in the winter or spring seasons.
Seasonal Occurrence The single state record is from the surprisingly late date (in winter/spring) of 16 April 2015.
Habitat Cold or cool waters, primarily found over the Continental Shelf in its North Atlantic range.
Behavior Known to frequently bow-ride and do acrobatic leaps, though a chunkier species than Atlantic White-sided Dolphin and thus not as acrobatic as that species. Typically occurs in groups of 5-30 individuals.
Comments Keith Rittmaster found the live male White-beaked Dolphin on Sand Dollar Island, between Carrot Island and Shackleford Banks, within Back Sound, in 2015. It was euthanized and is now a museum specimen (MME 18714). Details of this remarkable record are found in: Hairr, J. (2016). White-beaked dolphin found near Beaufort - a species heretofore undocumented from the shores of North Carolina. The Maritimes 5(2): 12-13.
