PHASES OF MOVEMENT OF A WALKING LION.
DOG WALKING.
The mode of progression in legless creatures is distinguished, too, by a lateral bending in and out. Snakes and eels, for example, as they proceed agitate their bodies in wave-like motions. The waves pass from the head to the tail, the fluctuations taking the form of rather large loop-like wrigglings of the elongated body. A spring-like coiling up and then an expanding—flexion and extension again—is the principle of the locomotory manœuvre in the snake.
VARIOUS KINDS OF WAVE MOTION.
A characteristic of many forms of movement which the animator gets in certain of his delineations.
The undulatory motive impulse of a creeping animal is somewhat like the sudden lashing of a whip, or the wave-like disturbance given to a rope when it is sharply and strongly shaken in a certain way.
