Marine Mammal Stranding Response: Welfare During Rescue

Stranded whales, dolphins, and seals require specialized response to minimize stress during rescue and maximize survival and welfare outcomes.

Key Facts

An estimated 2,000 cetaceans strand on US coasts annually
Hypothermia, sunburn, dehydration, and secondary injuries occur rapidly in stranded animals
Physical stress during human handling can cause cardiac arrest in large whales
NOAA authorizes only trained marine mammal rescue networks to respond to strandings
Return-to-sea success rates vary from near zero for large cetaceans to 70-80% for some seal species
Mass stranding events involving dozens to hundreds of animals are increasing in frequency

Welfare Considerations

Marine mammal strandings trigger acute welfare crises. Animals are often already compromised by disease, entanglement, or navigational failure, and the physical consequences of beaching — dehydration, overheating, weight compression on internal organs — progress rapidly. Response welfare priorities include cooling and shading, maintaining sternal position to protect lungs, and minimizing additional human-caused stress. For small cetaceans and seals, trained handlers can provide fluid support and prepare animals for release or transport. For large whales, welfare often means ensuring death is as rapid and peaceful as possible when survival is not feasible, using euthanasia rather than prolonged suffering. Triage systems that realistically assess survivability avoid prolonging suffering through futile rescue attempts.

What You Can Do

Never approach a stranded marine mammal without contacting trained rescuers first
Report marine mammal strandings immediately to the National Marine Mammal Stranding Hotline or local equivalent
Support marine mammal stranding networks through donations or volunteer training
Stay at a respectful distance from stranded animals to minimize additional stress before help arrives
