Morehead City, NC – A live Gervais’ beaked whale (Mesoplodon europaeus) was reported by beachgoers to the NC Marine Mammal Stranding Network in shallow water in Emerald Isle the afternoon of October 30, 2023 (pictured below). The NC Marine Mammal Stranding team arrived at the beach and confirmed the animal was a 10’ 9” (329 cm) long female calf and had expired.
Beaked whales are large, deep diving marine mammals. Little is known about Gervais’ beaked whale social structure and life history. Live sightings are unusual because the normal habitat for these animals is at the continental shelf edge and beyond, and they spend most of their time under water.
The dead stranded whale was removed from the surf. and transported to NC State University (NCSU) Center for Marine Sciences and Technology (CMAST) where it was chilled overnight. It was necropsied by marine mammal scientists, veterinarians, and university students.
Approximately 125 marine mammals strand on NC beaches each year, including whales, dolphins, porpoises, seals, and manatees. There are many reasons that animals wash ashore. Some include natural causes such as infectious diseases, parasites, cancers, and starvation. Some causes are from human interactions including entanglement in fishing gear (active and ghost), ship and boat strikes, and ingestion of plastic. Unfortunately, this young female whale died due to ingestion of plastic (see balloon photo below).
The collaborative team examined every tissue of this young whale during the necropsy, and all appeared normal however a pentagonal Mylar balloon was found blocking the digestive tract. Murder by balloon! Hopefully whoever released the balloon enjoyed it for the 5 minutes they held it
