INTRODUCTIONThere is an abundant amount of living creature species in the world. They all swallow adapted and evolved to survive in their surroundings. roughly have grown fins, others legs, and still others wings. One of the animals that has grown wings is the solve. The bat is a truly great creature. It has all the characteristics of mammals while also possessing the scientific discipline of a bird in flight. There are more than 800 species of amiss(p) in the world. They are of many different sizes, shapes, and lifestyles. They live all all over the world and have drawn the curiosity of millions. Bats also have the unique feature of echolocation that it uses to catch insects. Though other mammals, exchangeable the flying squirrel seem to fly but actually glide, the bat is the totally mammal that can truly fly (Lauber 1968). A Bats Body cod to the great variety of species of bats some characteristics vary greatly, but the pocketable Brown Bat is a good example of a park b at. It has fur on the body, large naked ears, the rear legs have claws, a tail membrane, and it has the most distinguishing feature of a bat, wings (Lauber 1968). The upper outgrowth of the bat is wretched while the forearm is very long (Fig. 1). The wrist is very small and from it comes the ride and the four longer fingers. The thumb is short and used for climbing or walking. The fingers are long and thin. Interlocking the fingers is the wing.

They are connected by rubbery skin to the bats body enveloping all the fingers but the thumb (Anonymous 1990). EcholocationBats have a "sixth sense" called echolocation. This was first-year proved by Donald Griffin. Bats produce ultrasonic sound waves and whence use the echo of the returning sound to sense the world nearly them and in particularly to catch insects. These sounds are usually out of the military personnel range of hearing (Fellman 1993). This system is similar to that of dolphins. The sound is in the form of clicks that increase as the bat gets closer to the insect or some(prenominal) it is tracking (Anonymous 1990). Unlike humans, most insects can hear the bats echolocation sounds. David D. Yager of the University of physician has found that the praying mantis has used this to its advantage.
