The Maryland Department of Natural Resources (DNR) is calling on residents and visitors to the Chesapeake Bay and Atlantic coast to watch for sea turtles and other marine animals showing signs of cold-stunning. This dangerous condition, caused by prolonged exposure to cold water temperatures, can leave animals weak, unresponsive, and vulnerable to injury or death.
Cold-stunning occurs in late fall and early winter when water temperatures drop significantly or rapidly within 24 hours. Sea turtles, unable to regulate their body temperature, become lethargic and may strand onshore or float listlessly in the water. The condition is life-threatening if not addressed quickly. This year alone, the Stranding Response Program has documented 858 cases of cold-stunned sea turtles nationwide as of December 12. Massachusetts reported the majority, with over 700 turtles stranded along its shores.
Although cold-stunning primarily affects sea turtles, other species like West Indian manatees are also at risk. In a notable case from November 2016, a cold-stunned manatee was found deceased at the Dundalk Marine Terminal. While manatee sightings are rare in Maryland, they underscore the need for vigilance.
If you encounter a sea turtle or marine mammal that appears sick, unresponsive, or stranded: maintain a safe distance, as approaching the animal could cause further stress or harm, and contact the Maryland Natural Resources Police Hotline at 800-628-9944. This hotline operates 24/7, ensuring trained professionals can respond promptly.
Both marine mammals and sea turtles are protected under federal law. The Endangered Species Act covers sea turtles, while the Marine Mammal Protection Act safeguards species like dolphins, whales, and manatees. Harassment, feeding, or collecting these animals—or their remains—can lead to fines, imprisonment, and the confiscation of vessels or property.
During cold-stunning season, Marylanders can play a vital role in protecting marine life. Boaters, anglers, and beachgoers are encouraged to stay alert for distressed animals. Reporting sightings ensures that experts can intervene, potentially saving lives. The Maryland Department of Natural Resources and its partners remain committed to marine conservation. Stranding Response Teams work closely with the National Oceanic and Atmospheric Administration (NOAA), relying on timely updates to monitor cold-stunning trends and respond effectively.
