Common name: Bat
Scientific name: Chiroptera
Features: In winter, they spend longer or shorter periods in hibernation during which all body activities such as breathing rate and heartbeat slow down, allowing little energy to be consumed. Survival is possible thanks to the body fat reserves accumulated during the warm season. They orient themselves in the dark by means of a sophisticated sonar: they emit ultrasounds, which bounce off surrounding objects and return to the animal that produced them in the form of an echo.
Curiosity: Bats are the second largest group of mammals after rodents.
