9. Hibernation Underwater: Surviving Cold Months
In winter, many amphibians enter a state of underwater hibernation, relying on cutaneous respiration to endure low temperatures and limited oxygen. Species like painted turtles and some frogs drastically slow their metabolism, absorbing dissolved oxygen directly through their skin. This remarkable adaptation allows them to survive months beneath ice-covered ponds, showcasing the flexibility of amphibian respiration in extreme environments. It’s a powerful example of evolution’s response to seasonal challenges. Reference
