February 29, 2024 — The following was released by NOAA Fisheries:
On Friday, February 23, 2024, NOAA Fisheries received a report of a 15-foot female white shark that washed up on the shores of Navarre Beach, Florida. Local partners quickly responded to the event and monitored the shark. The NOAA Fisheries Office of Law Enforcement then transported it to the NOAA Southeast Fisheries Science Center facility in Panama City, Florida. There, our scientists conducted a necropsy, or animal autopsy. While the team was not immediately able to determine the cause of death, they collected extremely rare samples from this enormous elasmobranch.
A “Great” Amount of White Shark Information
NOAA Fisheries researchers Michelle Passerotti, Heather Moncrief-Cox, and John Carlson led a team of eight biologists in conducting the necropsy over the weekend. They spent 9 hours collecting precise measurements, recording detailed notes, and dissecting the animal to gain valuable samples and information about the shark.
The white shark is one of the most well-studied shark species in the world. They gather in key feeding areas along coastlines throughout the world, which allows researchers to study them closely and predictably. However, most of these studies occur with live animals. Some samples—like vertebrae for ageing, stomach contents for diet studies, or reproductive measurements—can only be collected from a dead specimen. Opportunities to study dead sharks are incredibly important for science.
