What does bat mean?

"Bat" means "all kinds of blessings", symbolizing happiness, wishful thinking or endless extension of happiness.

Bats have strong flying ability, and they are also natural reservoirs of many viruses in human and animals. It can carry dozens of viruses and is the only mammal that has evolved the real flying ability. The evolution of its flight ability is closely related to a series of complex morphological and physiological changes.

Through in-depth analysis, the researchers found that a series of genes related to DNA damage checkpoints or DNA repair pathways in bats were strongly positively selected. They also found that genes related to skin elasticity and genes involved in muscle contraction evolved rapidly in bats, which may also help flying.

Extended data:

Bats can also talk, and some social signals can be used to attract mates, defend food, summon their own kind, and expel some animals that prey on bats. These signals are usually emitted at very low frequencies (sometimes people can hear them), so these sounds can travel far.

At the same time, these sounds will be different because of the difference of vocal bats. For example, when a baby bat is separated from its mother bat, it will send out a "lonely signal", and the mother bat will quickly distinguish whether it is her own baby or not according to the different sounds. In addition, many small bats are also sensitive to the echo frequency they often use.
