Turtles Enter a State of Suspended Animation to Survive Harsh Winters
Turtles Cut Metabolism, Body Temperature
Hibernating Turtles Lower Metabolism by 99%
In a study published Monday in the Proceedings of the National Academy of Sciences, researchers found that North American freshwater turtles can dramatically lower their metabolism and body temperature to survive the harsh winter months.
The turtles, which were studied in the laboratory, entered a state of suspended animation called brumation, which is similar to hibernation in mammals. During brumation, the turtles' metabolism slowed by 99% and their body temperature dropped to just above freezing.
The turtles were able to survive in this state for up to four months without eating or drinking. When the weather warmed up, the turtles emerged from brumation and resumed their normal activities.
The study's findings could have implications for the conservation of turtles, which are threatened by habitat loss and climate change. By understanding how turtles survive harsh conditions, researchers can develop strategies to protect them.
Conclusion
The ability of turtles to enter a state of suspended animation is a remarkable adaptation that allows them to survive in harsh conditions. This ability is a testament to the resilience of these animals and their ability to adapt to changing environmental conditions.
