First Known North Atlantic Right Whale Calf of the Season Washes Up Dead off North Carolina

The North Atlantic right whale calving season is off to a devastating start. The first documented newborn washed ashore dead on a barrier island off North Carolina, part of the Cape Lookout National Seashore. Each new right whale calf brings so much hope for this critically endangered species, and losses like this have a substantial impact on their recovery. Their population has been experiencing a significant decline and high juvenile and adult mortality in recent years.

On Friday, the carcass of the male right whale calf was discovered by the National Park Service along the remote island. Saturday morning a stranding response team conducted a thorough necropsy (animal autopsy) of the right whale calf.

The team included members from North Carolina State University, North Carolina Division of Marine Fisheries, North Carolina Maritime Museum, National Park Service, and University of North Carolina Wilmington. No evidence of human interaction was found during necropsy. Initial results suggest the calf died during birth, or shortly thereafter. Multiple genetic samples were collected in order to identify the calf's mother. Photographs and genetic samples from nearly all North Atlantic right whales are cataloged by the New England Aquarium.

North Atlantic right whalesare protected under the U.S. Endangered Species Act and the Marine Mammal Protection Act. Scientists estimate there may be fewer than 400 remaining, making them one of the rarest marine mammals in the world. The leading causes of the UME are vessel strikesand entanglement in fishing gear. The species has been experiencing an 'Unusual Mortality Event'since 2017, which is ongoing. Over the past three years, at least 32 dead and 13 seriously injured whales, have been documented in the UME. This represents more than 10 percent of the remaining population. This calf is the 32nd death and the 45th case overall in this UME.
