It turns out this is how dogs and cats control tongues to drink water

We all know, dogs and cats use their tongues to drink water, but have you ever wondered how they control their tongue?

1. For the first time, the breed of 'young and old' sand cat lives in the desert
2. Unbelievable story: The bitch adopts and feeds the 8-pig herd
3. 'Transfiguration' dogs turn green after drinking and bathing polluted river water in India

Associate Professor Sunny Jung and colleagues at Virginia Tech University (USA) used high-speed camcorders and mathematical models to shed light on the dynamics process that occurs when dogs drink water to help people have A better look at how to "refresh" the puppy.

The whole process of drinking the dog's water depends on the tongue part. Then, it will bend its tongue backwards and push the tongue into the liquid, and quickly pull the tongue back to the mouth. This action will create a water column below the tongue, the inertial force will be introduced into the mouth.

According to calculations by experts, the dog has created a force of about 8 times the gravity to form a strong water column to pull water up.

From the outside, we see dogs and cats have the same way of drinking water, but in fact they are not.

According to Sunny Jung's research, cats also dipped their tongue into the water but they only slightly bent the tip of the tongue into a J-shape and took the tip of the tongue to shock it, not bending the tongue like a dog.

The speed of cat's tongue movement is extremely fast about 1m / s, which allows cats to lick water at least 4 times per second.
