"Since nearly every one is obliged to do some walking, certain muscles of the legs are sure to get some exercise. In ordinary walking, however, less than one half of the hundred muscles in the legs are brought into use. To get the best exercise out of walking one must walk as fast as possible, and let the arms swing to and fro at the sides." —Davison, 1910

The prominent head is joined to the body by a distinct neck, and the body itself is short, generally more or less rounded in shape, and unprovided with side or lateral fins. They have attained a notoriety from tales circulated concerning their ferocity and the existence of gigantic members of the genus, though the largest cuttle-fishes that have been met with have belonged to other genera." &mdash; Winston's Encyclopedia, 1919
