Bats are extremely developed. They can fly freely and accurately catch food at night or in very dim environment. The most basic means is to use echolocation.
Experiments show that most bats use ultrasonic pulses from their throats to locate themselves. But this is different. Some large fruit bats, such as brown fruit bats, have special echolocation ability. They use the sound of licking their tongues as the basis for sound localization, so bats can hear ultrasonic waves.
Extended data:
This research on bat genes started from 20 1 1 and took nearly a year. It was jointly completed by shenzhen huada gene research institute, Australian Institute of Animal Health, Wuhan Institute of Virology, Chinese Academy of Sciences, China Academy of Sciences, and US Naval Medical Research Center.
The researchers chose two species of bats that were far apart-the big bat, the central flying fox, and the small bat, the David mouse-eared bat, and sequenced their whole genomes.
It is found that the bat's powerful antiviral ability is rooted in its genes. Comparing more than 60 genes related to the natural immune system of mammals in bats, it is found that nearly half of the genes in bats have undergone rapid evolution.
In other words, compared with other species, their gene sequences have undergone many "unique mutations", which may lead to changes in gene functions, which may make bats more resistant to viruses.
