Case History

This juvenile green sea turtle was found cold stunned and washed ashore in Seabrook Island. South Carolina Department of Natural Resources permitted volunteers responded and transported the sea turtle to the Aquarium for treatment.

Treatment

Upon arrival, Rose was alert and reactive when handled. This little green was cold to the touch and had an internal body temperature of 51 degrees Fahrenheit as well as a decreased heart rate.

Through a combination of microchip and visible identification markers, we were able to determine that this turtle had been previously encountered during a different cold stun event. After being rehabilitated and released from another facility, Rose unfortunately later found her/his way back into colder waters and was once again affected by the chilly temperatures. Unfortunately, this time, the thermal impacts also damaged the carapace (top shell), and resulted in areas of missing keratin and exposed bone. We took radiographs to look not only at the bone involvement, but also at the condition of the lungs. Sea turtles suffering from cold stunning often present with pneumonia, and Rose’s breaths sounded raspy. We did see some bronchial patterns that may indicate pneumonia, but Rose was too active to sit still for a proper CT scan.

While it is a good sign that Rose is strong and in good body condition, we could not risk sedating her/him for imaging due to the poor blood values that resulted from the hypothermia. We will follow up with a CT scan once Rose is stable enough to be safely sedated. We treated Rose with fluids and vitamins and allowed Rose to rest overnight in a climate-controlled room. By setting the thermostat accordingly, we can make sure that Rose’s body temperature gradually and safely increases to the desired level. Once the body temperature is closer to 70 degrees F, Rose will be metabolizing better and we can start further treatments, like antibiotics.

Updates

March 24, 2025: Rose’s body temperature slowly warmed over the past couple of days and s/he became more active. Once Rose’s temperature was within a couple degrees of the tank water temperature, we were able to swim test this little green in a half-full tank. Thankfully, Rose looks strong and is able to safely stay in the water! We will begin slowly offering food items and administering antibiotics to begin to treat the shell damage. Fingers crossed for this green sea turtle!
