However,legends are also known that batsalso have positive meanings to the gods. Bats are found in several European family crests. In England, the bat is black on silver, and in France it is gold on blue. The Swiss coat of arms shows a black bat and a green pomegranate on a gold background. In China, bats are revered as a symbol of longevity and happiness.
Bats range in size from 3 to 8 cm.
Insectivorous, bats hunt many insects and other invertebrates. Bats have the ability to lower their body temperature to the temperature of their environment and can also maintain a high body temperature when active. To become active, bats first warm up to their operating temperature . Bat warm-up is manifested by intense shivering,
which may occur all at once or gradually, depending on the bat species. Communication through sound is very important for bats.
Bats can produce a wide variety of sounds. Sounds that are audible to humans are recorded as chirps, squeaks, hisses, and high-pitched whistles. Other sounds are produced in a variety of other ways. During mating season scent communication, the scent glands on the cheeks of male bats become enlarged. They spend much of their life and activity cleaning their bodies. When bats transmit echolocation signals, they turn their heads and open their mouths. These signals are either inaudible to humans or are only heard as a soft “whoosh” sound. They are excellent flyers and can maneuver very well in the air. But they also move well on the ground and can fly out of it if they are not too tired, injured, or young. But they are also good swimmers and can swim with their wings open.
