Cold Stunning in Sea Turtles | Animal Welfare Hub

Cold stunning is a seasonal threat to sea turtles in temperate waters, causing mass stranding events requiring coordinated rescue response.

Key Facts

Cold stunning occurs when sea turtles are trapped in cooling waters as temperatures drop below 10 degrees Celsius
Thousands of Kemp ridley sea turtles strand on Cape Cod beaches each autumn during cold stunning events
Stunned turtles cannot swim, breathe effectively, or maintain body temperature
Successful rescue and rehabilitation rates exceed 80% with proper warming and veterinary care
Climate change is shifting sea turtle distribution northward, potentially increasing cold stunning exposure

Welfare Considerations

Cold-stunned turtles are conscious but paralyzed — a state of significant welfare concern involving both cold stress and vulnerability to predation and injury. Mass stranding events require rapid community response. Rehabilitation has proven highly effective, making cold stunning one of the more tractable wildlife welfare challenges.

What You Can Do

Report cold-stunned sea turtles immediately to local wildlife authorities rather than attempting rescue yourself
Volunteer with sea turtle stranding networks in cold-stunning-prone coastal areas
Support marine wildlife hospitals that treat cold-stunned turtles during peak stranding seasons
