Bats are the only type of mammals that have evolved their ability to fly. There are more than 900 types. Most of them also have a keen audit orientation (or echo positioning) system. Most bats are eaten in insects. Because bat prey a large number of insects, it plays an important role in the balance of insect reproduction, and may even help control the pests. Some bats also eat fruits, pollen, nectar; tropical America's blood -sucking bats are eaten by mammals and large birds. These bats sometimes spread rabies. Bats are global distribution. In tropical areas, the number of bats is extremely rich, and they will integrate large groups in people's houses and public buildings. The size of the bat is very different. The biggest vampire fox wing exhibition is 1.5 meters, while the wing exhibition of Kitty's pork nose bat is only 15 cm. The color, fur texture and face of bats are also very different. The wing of the bat is evolved from the forelimb during the evolution. Except for the thumb, the forelimbs are extremely elongated, and there is a flying film connected from the ankle of the lower limb to the lower limbs from the front of the forearm and the upper arm. There are claws at the end of the thumb. Most bats also have two layers of membranes between the legs, composed of dark bare skin. The kiss of the bat is like a rodent or a fox. The outer ears are protruding forward, usually very large, and flexible activities. Many bats also have nasal and leaves, composed of skin and connective tissues, surrounded by nostrils or above the nostrils. It is believed that the nasal and leaves affect sound and echo positioning. The neck of the bat is short; the chest and shoulders are wide and the pectoral muscles are developed; the hip and legs are slender. Except for the wing membrane, the bat has hair all over the body, and the back is densely gray, brownish yellow, brown or black, while the abdominal tone is lighter. Bats inhabited in the open area, with spots or mixed colors on the fur, and the colors are different. Bat feeding habits have different feeding habits, or predatory, or help to spread and spread fruits, which affects the order of nature. Vampire bats is a serious problem for humans. The feces of insects have been used as fertilizer in agriculture. The sex cycle of the entire bat group is synchronized, so most of the mating activities occur within several weeks. From 6, 7 weeks to May, June. Many types of feeds move to a special breeding place after pregnancy. Bats are usually 1 to 4 babies per nest. When the child is born, it is hairless or less hairy, and often cannot be listened for a period of time. The child is taken care of by the authenticity for 5 weeks to 5 months, and it is determined by different types. Almost all bats rest in the daytime and foraged at night. This habit is convenient for their fell asleep prey, and they are not harmed by other animals or high temperature sunlight. Bats usually like to inhabit places in isolation, such as caves, gaps, caves or buildings, and there are also inhabiting trees and rocks. They are always hung upside down. They generally gather into groups, from dozens to hundreds of thousands. Bats with echo positioning capabilities can produce short and high -frequency sound pulses. These sound waves reflected back when they encounter nearby objects. Bat heard the echo of reflection, which can determine the position and size of the prey and obstacles. This ability requires a close combination of high -sensitive ears and vocal centers with the auditory center. Bat individuals may also communicate with sound and pulse. A small number of bats rely on smell and vision to find food. Although they have universal glue, they look like birds. But they do not have feathers and do not have eggs. The cause of mammals: females produce children, nurture with milk
There are more than 900 types of bats in the world, and there are about 81 species in my country. It is the second largest group of rodents in mammals.
