Mar 19, 2019 · In both instances, the procedure is the dissection of a body to determine why the individual died. Here at Cornell Wildlife Health Lab, we perform necropsies to determine the cause of death so that we can keep an eye out for diseases and toxins that can impact wildlife, domestic animals or humans.
Aug 13, 2021 · Every marine organism that we study contributes to a larger research database that future scientists can use. That is why, whilst clearly a sad event, the scientific opportunity to perform a necropsy can provide vital information in keeping current populations thriving.

A necropsy is the examination of the dead body or carcass of an animal, similar to an autopsy conducted on humans.
Scientists and veterinarians routinely conduct necropsies of marine mammals as part of a conservation management program. Necropsies of marine mammals (e.g., seals, sea lions, dolphins, and whales) can provide significant information regarding the health of the individual animal, the species, and the ocean environment.
NOAA Fisheries’ Marine Mammal Health and Stranding Response Programoversees and authorizes highly skilled and trained members of the National Marine Mammal Stranding Response Network to respond to stranded marine mammals and conduct necropsies to investigate causes of death. The Network is made up of more than 120 professional organizations, includ...
Marine mammal carcasses may strand or come ashore in a variety of places, including remote islands, on protected lands, or private lands. Carcasses can also be found floating in the ocean, and may be towed to shore for examination or examined at sea. The Network responds, when safe and feasible, to document and recover carcasses. It does not and ca...
Necropsies on large animals, such as whales, are resource intensive. They may require heavy machinery such as front loaders and excavators to move larger animals to a safer location and to help position the animal for better examination.
Animals may have been exposed to harmful contaminants or carry diseases that are transmissible from the animal to humans. Necropsy team members often wear personal protective equipment such as gloves, gowns, or aprons to prevent excessive exposure to the carcass. They work in close proximity with one another and must be mindful of their surrounding...
Team members often collect biological samples from many parts of the animal. These include skin, blubber, muscle, baleen/teeth, and internal organs. These samples help us understand marine mammal biology, pathology, and sometimes cause of death. Strandings sometimes involve human interactions, such as vessel strikes, entanglements, gunshots, or pol...
A necropsy involves visually examining the carcass, both externally and internally, evaluating samples by microscopic analyses, and a variety of other laboratory based tests—the results from necropsies are rarely (if ever) immediate. Necropsy teams may have preliminary information on the animal’s health status based on the initial visual exam. But,...
The monetary and in-kind costs associated with a marine mammal necropsy are typically covered by the individual Stranding Network organization that conducts the response. In some situations, such as during Unusual Mortality Event investigations, partners may receive some additional monetary support from NOAA Fisheries. Our Stranding Network partner...
The Marine Mammal Protection Actauthorizes emergency response to marine mammal species and data and sample collection through formal stranding agreements issued to the Stranding Network. However, it does not mandate conducting necropsies. NOAA Fisheries does not require Stranding Network partners to conduct stranding responses or necropsies for eve...
Dec 16, 2020 · The Scientist: In your paper, you note that necropsy findings have never before been evaluated to understand causes and trends in orca mortality. Why do this now? Joseph Gaydos: We’ve seen how valuable this type of data analysis is for understanding shifts in populations of marine mammals such as gray whales.
When stranded animals die, experts perform a necropsy—an animal autopsy—to learn more about why the animal died and to inform future responses. A necropsy also can tell researchers what an animal ate, and whether it was or had been pregnant.
Aug 26, 2010 · Forensic pathologists — physicians trained in the study of diseases and abnormalities — perform autopsies with the assistance of autopsy technicians (sometimes called "dieners," from the German...
May 9, 2014 · A necropsy is performed to determine the possible cause of death and/or to detect induced or coincidental pathological alterations in tissues. The tools to perform a necropsy will vary not only by species, the type of dissection that is required, and personal preferences.
