The winged hands, the only mammals, have mastered the art of waving flight. Their front extremities are transformed into wings, elongated bones of fingers, like spokes, support the eardrum stretched between the front and hind legs and tail. The front finger of the wing is free from the membrane and ends with a chain claw used for climbing. In the skeleton of the arm wings, as in birds, there is a keel to which powerful breast muscles are attached.
...THE BEHAVIOR OF THE HAND WINGS...
Winged Hand-wings are a very large group of about 1,000 species. This includes bats and more primitive wings. Hand-wings are common all over the world, especially in the tropics and subtropics. Different species have body lengths ranging from 3 to 42 cm. All these animals are active at dusk or at night, and spend the day in the crowns of trees or in shelters - in attics of houses, hollows, caves, where often form huge colonies. Animals living in temperate latitudes hibernate for the winter or fly to warmer areas.
Winged hands are well adapted to a long active flight. Small bats outperform most birds in maneuverability. In addition, hand-winged bats deftly climb vertical surfaces, clawing at fine irregularities. Bats use echolocation to navigate in the dark. They emit a series of ultrasonic squeaks and determine the location, size, shape and even the smallest details of the surface by their reflection from objects. In this way, hand-winged people not only find food but also turn in time so as not to bump into an obstacle in flight.
BAT NUTRITION
Some tropical species are fed on by insects and some by fruits of trees or flower nectars (some tropical species have adapted to pollination by hand-wings only). In the South, there are a number of species of tropical plants that have adapted to pollination only by hand-wings.
and Central America have bats and fishermen. Many people don't like and are afraid of bats, but most of them (especially insect eaters) do a great deal of good by destroying pests of agriculture, as well as mosquitoes and mosquitoes.
The vampire family mainly feeds on the blood of warm-blooded animals (hence the name of the family). They silently sink onto the sleeping victim's body or climb up to it on the ground, cut through the skin with sharp, forward-facing incisors and suck on the wound. The victim usually does not feel the bite because the vampire saliva contains painkillers. Thanks to the anticoagulant (a substance that prevents blood clotting) in the saliva, the blood continues to flow from the wound for several hours.
The vampire's tongue is designed so that the sides of the vampire are wrapped up to the bottom, forming a tube through which the animal sucks in the blood. A vampire drinks half his own body weight in 24 hours. Vampires are also dangerous because they carry rabies and other diseases that are dangerous for humans and pets.
HAND-WINGED REPRODUCTION (BATS)
Hand-winged individuals breed once a year. Usually, the female brings 1-2 calves, which are immediately hanged from its nipples located on the chest. The calf holds onto the mother's nipples with milk teeth. He is in this position all the time in the first days of life. The offspring are taken care of only by the female. In some species of crank wings (e.g. wings), the female carries a newborn calf all the time
on himself until he learns to fly. Other types of hunting leave their offspring in shelters where they form groups, like kindergartens.
INTERESTING FACTS ABOUT BATS
A vampire often attacks pets and people.
The ears are different from other bats in that they have very large ears, which are almost the same length as the body length. They have great hearing.

Wingspan of flying foxes reaches 170 cm, it is the largest representatives of the winged foxes, belonging to the group of winged wings. These animals do not have the ability to echolocation and are guided by a sense of smell and sight in their search for food. They feed on the flesh of juicy fruits. They lead a twilight and nightlife and spend the day hanging head down on the branches of trees, and one tree often gathers hundreds of individuals.
