Tail-wagging in Animals
The levator ani muscles, in quadruped animals with tails, are responsible for moving the tail around in the act of "wagging." These muscles are not as strong as their human equivalents, as tail-wagging is less demanding than the support function that the muscles serve in humans.

Famous quotes containing the word animals:
“From the oyster to the eagle, from the swine to the tiger, all animals are to be found in men and each of them exists in some man, sometimes several at the time. Animals are nothing but the portrayal of our virtues and vices made manifest to our eyes, the visible reflections of our souls. God displays them to us to give us food for thought.”
—Victor Hugo (1802–1885)
