Lämminverisillä

Lämminverisillä is a Finnish term referring to warm-blooded animals. This biological classification encompasses a vast majority of the animal kingdom, including all mammals and birds. Warm-blooded animals, also known as endotherms, are characterized by their ability to maintain a stable internal body temperature regardless of the external environment. This internal regulation is achieved through metabolic processes, such as breaking down food for energy, which generates heat.

Unlike cold-blooded animals (ectotherms), which rely on external sources like sunlight to regulate their body temperature, lämminverisillä can thrive in a wider range of climates. This independence from ambient temperature allows them to be active at different times of day and in various weather conditions. Maintaining a constant internal temperature requires a significant amount of energy, which is why warm-blooded animals typically have higher metabolic rates and often consume more food. This physiological advantage has contributed to the evolutionary success and widespread distribution of mammals and birds across the globe.
