Do bats have eyes?

Bats are the only mammals that have evolved the ability to fly. There are 19 families, 185 genera and 961 species. They are distributed all over the world except in the polar regions and some islands in the ocean. Their forelimbs have changed into wings, flying in the air at night, eating mosquitoes, moths and other insects, and a few eat fruit or suck the blood of other animals. Let's take a look at whether bats have eyes.

Do bats have eyes?

Bats have eyes, but they are very small in order to work effectively at night or in dark caves. In the past, many people said that the poor eyesight of bats was in fact a big misunderstanding. Many scientists have pointed out that the eyesight of bats is not poor. Different species of bats have different eyesight, and the use of ultrasonic waves by bats is not necessarily related to their eyesight.

Are bats poisonous?

Bats are not poisonous, but bats do carry at least 14 viruses that can infect humans or animals, including rabies, Hendra virus, Nipah virus, "Hanta" virus, etc., especially Nipah virus, more than 50% of people who are infected will die. Bats carry the virus, and it has been confirmed that there have been at least two outbreaks of infectious diseases in recent years, one in Australia, where Hendra virus is first transmitted from bats to horses and then to humans. Another time in Malaysia, the Nipah virus was transmitted from bats to pigs and then to humans.

How to locate the bat?

Bats have a high ability to distinguish sounds and have biological wave positioning structures in their ears to identify objects by emitting biological waves and distinguishing objects according to their echoes. When flying, a biological wave is emitted from the mouth and nose that cannot be heard by humans, which bounces back when it encounters insects. After receiving, the ear will know the exact location of the prey, thus going to capture, the sound frequency that can be heard can reach 300 kHz, while that of humans is generally less than 14 kHz.
