How bats reproduce.

Bats are a class of mammals that have evolved the ability to fly. Except for some islands in the polar regions and oceans, bats are distributed all over the world, with the largest number of bats in the tropics and subtropics. So how do bats reproduce?

How do bats reproduce

Bats are viviparous animals. The nutrients needed for embryonic development can be obtained from the mother until birth. Bats usually give birth to one to four cubs per nest. The cub is born hairless or less hairy and cannot be seen or heard for a period of time. The cubs are taken care of by themselves for 5 weeks to 5 months, according to different types.

II. Flight characteristics

Bats are animals that can really fly. Although they do not have feathers and wings like birds, and their flying skills are much worse than birds, their forelimbs are very developed, and their upper arms, forearms, metacarpal bones and phalanges are all very long. And from it a thin and hairy soft and tough skin membrane from the end of the phalanx to the humerus, body side, hind limbs and tail, forming the bat's unique flying organ-pterygoid. Bats use waves to determine whether there are obstacles ahead and to change their flight path. In the past, many people said that bats had poor eyesight, but it was actually 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 ultrasound by bats has nothing to do with their eyesight.

III. Natural enemies of bats

The main natural enemies of burrowing bats are snakes and lizards, and the natural enemies of arboreal (some fruit bats) are also some birds of prey and cats. Other natural enemies of bats are humans, such as the great bats in Guam, which became extinct because of the predation of the local people.

IV. Bat feeding habits

Bats eat a wide range of animals, some species like nectar, fruit, some like to eat fish, frogs, insects, feed on animal blood, and even eat other bats. Generally speaking, large bats generally feed on fruit or nectar, while most small bats prey on insects.

There are all kinds of bats to eat: fruits, fish, pollen, and even blood. Most bats prey on insects when they fly at night, and each bat can recognize its own sound waves, indicating that even if it hunts with other bats, it will not be disturbed by other sound waves.

Bats are one of the most widely distributed and evolutionarily successful mammal groups in the world. Except for the remote desert islands in the north and south poles and the ocean, all kinds of terrestrial ecological environment on the earth are utilized by them.
