What Are the Health Concerns of Bat Guano?
Bats are pterodactyls. Pterodactyls are the second largest group of animals after rodents. They are a class of mammals that have evolved to have real flying ability. There are 961 species of 185 genera in 19 families. Some islands in the polar and oceans are distributed all over the world, with the largest number of bats in the tropics and subtropics. Most bats rest during the day and forage at night. [1]
- Bat wings evolved from forelimbs during evolution, and consist of skin (wing membrane) connected between their slender claws; bats' snouts are like rodents or foxes. The outer ear protrudes forward, is large, and is very flexible. Bats have short necks, wide chests and shoulders, and fleshy breasts
- The sexual cycle of the entire bat population is synchronized, so most mating activities occur within a few weeks
- Bats are one of the most widely distributed and most successfully evolved mammals in the world. Except for the remote islands in the north and south poles and the ocean, all terrestrial ecological environments on the earth are used by them. During the evolution process: they fled to the sky to avoid competition with other land and marine beasts, and the highly evolved echolocation system allowed bats to avoid competition with most birds in the air and to use a unique environment in the Niche-the dark sky. [1]
- Like other animals, many bats are becoming scarce in nature and becoming extinct. Insecticides and wood protection agents used to destroy insects killed them during hibernation, and many misconceptions caused humans to hunt them in large numbers. Some species of dwelling hollow trees have been cut, and the ruins have been demolished or rebuilt so that they cannot survive. Bats play an important role in maintaining the ecological balance of nature. Various insectivorous bats can destroy a large number of pests such as mosquitoes, night moths, scarabs, nuns and other insects. They can prey more than 3,000 overnight, which is beneficial to humans. The faeces collected by bats are also good fertilizers, useful for agricultural production. Processed bat dung is called "
- Bat genomics research completed by Chinese and foreign scientists is published online in Science. Scientists' comparative analysis of bat genomes of two different groups reveals the adaptive mechanisms of bat flight and immune system, clarifies the molecular diversity mechanism of different bat groups, and provides research for bats and other mammals in biology and evolution. Provide new ideas. [3]
- 1 Some bats can fly at speeds of more than 50 kilometers per hour.
- 2 Some bats can fish. Mexican rabbit-lip bats can catch more than 30 small fishes in one night.
- 3 The pig-nosed bat has a wingspan of only 14 cm, and the wings of the flying fox, which are as large as a puppy, are 2 meters wide.
- 4 Bats can capture and resolve 250 echoes in 1 second. (Note: Sound waves count as one group at a time.)
- 5 Since autumn, the bat has accumulated a layer of fat in the lower abdomen, and before the hibernation, it becomes more than 1.5 times the weight in the summer.
- 6 A 20-gram insectivorous bat can eat 1.8 to 3.6 kilograms of insects a year.
- 7 A bat colony is made up of 100 bats.
- 8 Bats have good vision and have not deteriorated. It emits a sound wave higher than 20,000 Hz by the mouth, called "ultrasonic", which is inaudible to humans. Ultrasonic waves will bounce back when they encounter obstacles and pass into the bat's sensitive ears. The bat judges whether it is eating or fleeing by judging obstacles and so on through its brain.
- 9 On December 7, 2017, Shi Zhengli, a researcher at the Wuhan Institute of Virology of the Chinese Academy of Sciences and director of the Xinfa Infectious Diseases Center, said that bats are the source of SARS virus.
