Jääkilpade

Jääkilpade, often translated as ice turtles, is a colloquial term used in certain regions to refer to specific freshwater turtle species that are adapted to cooler climates or exhibit behaviors associated with colder periods. The term is not a formal scientific classification. These turtles may be found in northern latitudes or inhabit lakes and rivers that experience significant seasonal temperature fluctuations. Their adaptations can include a slower metabolism during colder months, allowing them to survive periods of reduced activity, sometimes referred to as brumation, which is analogous to hibernation in mammals. While they are cold-blooded, meaning their body temperature is regulated by their environment, these species possess physiological mechanisms to cope with lower temperatures, such as specialized antifreeze proteins in their blood or the ability to respire anaerobically for extended periods. Common species sometimes referred to by this informal name might include certain members of the Emydidae family, known for their adaptability. Their diet and breeding cycles are often closely tied to the warmer seasons, with activity increasing significantly as temperatures rise.
