In fact, whiskers or as they are also called "vibrissae" exist in all animals and not only on the head, but also on the chest, neck and stomach. And they fulfill the function of touch, which helps animals move around, distinguish living beings from non-living things, etc.

For example, a mole has a whole set of vibrations that react to touch and air waves in narrow burrows. But in the gerbil, the vibrissae are located on the muzzle, 10 cm long and directed forward.

Under the water

In this environment, as many animals have a mustache,Beginning with beavers and ending with seals. They are located on the jaws and muzzle. And they come to the rescue when they pick up the muddy mud from the bottom, because these animals have to look for food at the bottom. For example, a whale has 250 of them, they need it for those cases when food is near, but because of the location of their eyes, it can not see it. In addition, whale whales can catch the slightest touch of even the smallest cancer.

On the ground

It turns out that these representatives need no less mustaches than the rest of the animal. They are located on the upper jaw, on both sides of the nose, on the chin and head. By touching, to any object, they identify not only whether this living being is alive or not, but also its size and even weight. Thus, the cat recognizes how dangerous this or that creature can be.
