Abstract: An adult 273.7-kg, 266-cm male white-beaked dolphin (Lagenorhynchus albirostris) stranded in Beaufort, North Carolina, on 16 April 2015 at 34.698125 N, -76.650476 W. Morphometrics, gross necropsy, and histopathologic evaluation were performed. Bilateral adrenal gland tumors (pheochromocytomas) were found and may have contributed to stranding. This is the first recorded white-beaked dolphin specimen to strand along the North Carolina coast, and it is the most southerly reported stranding of a white-beaked dolphin in the world.
