Although animals have never evolved wheels for locomotion (see Rotating locomotion in living systems), a small number of animals will move at times by rolling their whole body. Rolling animals can be divided into those that roll under the force of gravity or wind and those that roll using their own power.

Famous quotes containing the word rolling:
“Look, we’re all the same; a man is a fourteen-room house—in the bedroom he’s asleep with his intelligent wife, in the living-room he’s rolling around with some bareass girl, in the library he’s paying his taxes, in the yard he’s raising tomatoes, and in the cellar he’s making a bomb to blow it all up.”
—Arthur Miller (b. 1915)
“I caught this morning morning’s minion, king-
dom of daylight’s dauphin, dapple-dawn-drawn Falcon, in his riding
Of the rolling level underneath him steady air, and striding
High there, how he rung upon the rein of a wimpling wing
In his ecstasy!”
—Gerard Manley Hopkins (1844–1889)
“It is only when we are very happy that we can bear to gaze merrily upon the vast and limitless expanse of water, rolling on and on with such persistent, irritating monotony, to the accompaniment of our thoughts, whether grave or gay. When they are gay, the waves echo their gaiety; but when they are sad, then every breaker, as it rolls, seems to bring additional sadness, and to speak to us of hopelessness and of the pettiness of all our joys.”
—Emmuska, Baroness Orczy (1865–1947)
