On January 8, 2023, an aerial survey team from the Clearwater Marine Aquarium sighted a heavily entangled North Atlantic right whale approximately 20 miles east of Rodanthe, North Carolina, per an update from NOAA.
There were several wraps of line around the mouth and tail, with additional line trailing behind the whale. After reviewing documentation of this new entanglement case, NOAA Fisheries biologists have made a preliminary determination that it meets the criteria of a “serious injury.” This means the whale is likely to die from this injury.
Scientists with the New England Aquarium identified the whale as right whale #4904, a 4-year-old juvenile female. The Aquarium manages the North Atlantic Right Whale Catalog to track the identification and sighting history of each right whale. This entangled whale is the daughter of right whale #1204, an adult female named “Spindle,” who was recently seen with a new calf off St. Catherines Island, Georgia.
The last known sighting of right whale #4904 was in May 2022 in Massachusetts Bay, and she was not entangled at that point. NOAA Fisheries and their partners reviewed initial images from January 8, which showed her to have numerous wounds across her body and whale lice on her head.
Entanglement response teams did not mount a response at the initial sighting because it was too late in the day and the whale was too far from shore. However, as conditions permit, NOAA Fisheries will work with authorized responders and trained experts to resight her. They will further document the entanglement, and determine if an entanglement response will be possible.
Right whale #4904 is the 94th right whale documented in the ongoing North Atlantic right whale Unusual Mortality Event, which was first launched in 2017. This UME includes dead, seriously injured, and sub-lethally injured or ill whales. Researchers estimate there are fewer than 70 reproductively active females remaining, and approximately 325-335 North Atlantic right whales left in the world, from Canada to Florida.
A one-year-old male North Atlantic right whale, identified as #2022CalfOf2614, was also spotted off the Avon Pier on Sunday, January 8. For more information on the Avon sighting, click here.
