Bats have a special ultrasonic sense organ which enables them to move in the dark without bumping into the smallest obstacle. Our ears also have limits for the intensity of sound they can tolerate. If sound is weaker than zero decibels we no longer hear it. Certain animals, however, can hear very weak sounds at long distances. Above 100 decibels, even brief exposure can cause permanent damage.
Some animals have a more highly developed taste sense and can taste whether vegetals are toxic.
We can distinguish some 10,000 different odors. This is provided, of course, that our noses are not blocked by colds or allergies. Gifted people working in perfume laboratories have extremely well developed smell organs. Our touch organs are relatively underdeveloped, except in musicians and other people where touch is part of their profession. Generally speaking, Western doctors can feel only one pulse.
