Here's a breakdown of the key features:
* Reduced metabolic rate: The animal's body processes slow down significantly, leading to decreased heart rate, breathing rate, and body temperature.
* Lowered body temperature: The animal's body temperature drops significantly, often close to the ambient temperature.
* Increased torpor: The animal becomes inactive and unresponsive to external stimuli, entering a state of deep sleep.
* Energy conservation: This state minimizes energy expenditure, allowing the animal to survive on stored fat reserves.
* Triggering factors: Hibernation is typically triggered by environmental factors like decreasing day length, dropping temperatures, and food scarcity.
* Duration: The duration of hibernation varies depending on the species and environmental conditions, ranging from a few weeks to several months.
Important note: Hibernation is not the same as sleep. While sleep involves a decrease in metabolic rate, it's not as drastic or prolonged as hibernation. Furthermore, animals in hibernation can't be easily awakened, while animals in sleep can be awakened relatively easily.
