The complete county distribution, spread across 11 North Carolina counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Tamanend’s bottlenose dolphin reports follow North Carolina’s shallow coastal water, from Cape Hatteras inlets into Pamlico and Albemarle sounds. Those sheltered estuaries separate its local pattern from the deeper-water common bottlenose dolphin. Shoals, channels, and dock structures can help groups crowd fish into tighter schools.

The record needs an extra caution because scientists only recently split the two bottlenose dolphin species. Older North Carolina observations may remain under the broader common-dolphin name, and offshore sightings can be difficult to assign. The reported total is therefore neither a population count nor a complete history of coastal presence.
