Cold Stunned Sea Turtles’ Care Continues

The four sea turtles being rehabilitated at the Greensboro Science Center are getting stronger and healthier every day. The team of aquarists and our vet are monitoring the turtles to assess when they will be ready for release. Their actual release date will be contingent on the state’s recommendation. The aquarists continue to provide care and evaluate the behavior of the turtles to make sure they are acting as healthy, wild sea turtles.

Aquarist & veterinarian examine sea turtles

Sea turtle swimmingHealthy sea turtles swim freely in their space; are relaxed and not skittish. Fortunately, our turtles are utilizing all the water in the tanks. They swim around, across, and throughout the water column. Sea turtles are reptiles and they must surface to breathe air, so you would think that they would float like humans do when they fill their lungs with air. But divers have observed how sea turtles appear to lie still and float under the water surface, whereas humans naturally rise and float on the surface. Sea turtles can regulate the volume of air in their lungs, so as they dive, the lungs compress and they become less buoyant, or neutrally buoyant, and essentially “float” in the water column. A healthy, neutrally buoyant turtle will float in the water parallel to the surface, but not necessarily on the surface. A turtle that isn’t able to float parallel is a sign something is wrong.

In addition to good healthy behavior, the team monitors the turtles’ diet. Aquarists feeding the turtles daily and they have noticed that the turtles’ appetites are growing. Adult turtles are herbivores (plant eaters), feeding on sea grasses and algae, but as juveniles they have a more diverse diet. Juveniles are omnivores (plant and meat or animal eaters), including a diet of jellyfish, crustaceans, and sponges. At the Center, the turtles are receiving a diet that consists of fish, squid, some lettuce and gel food. Gel food is a vegetarian alternative to their diet. They are not so impressed with this option, but they have readily accepted the other items!
