 4 1      |         not more, but bloodless animals more than four, and generally
 5 1      |          and generally why some animals are footless, others bipeds,
 6 3      |      questions in order.~Now of animals which change their position
 7 3      |       once, for example jumping animals, others move one part first
 8 3      |   example walking (and running) animals. In both these changes the
 9 4      |         plants too, not only in animals. And this distinction is
10 4      |       in position other than in animals. Still they are similarly
11 4      |      are not only alive but are animals have both a front and a
12 4      |         parts are the back.~All animals which partake not only in
13 4      |        some than in others. For animals which make the aforesaid
14 4      |    progress, like some footless animals (for example snakes and
15 4      |     murex and the ceryx. As all animals then start movement from
16 4      |    higher degree than the other animals; now the right is naturally

19 5      |    hands and arms in the other. Animals which have the superior
20 5      |     ground under our feet.~Some animals, too, have the front and
21 5      |          polypods, and footless animals to the intermediate part,
22 5      |          polypods, and footless animals again have their superior

24 7      |     locomotion belongs to those animals only which make their changes
25 7      |     their structure, or to such animals par excellence. Moreover,
26 7      |       peculiarly to Sanguineous animals, we see that no Sanguineous

30 7      |         snakes, and among water animals of eels, and conger-eels
31 7      | snakelike. However, some marine animals of this shape have no fin,
32 8      |        evident that Sanguineous animals like snakes, whose length

34 9      |    which it stands.~Of limbless animals, some progress by undulations (
35 9      |        subtends them undulating animals could not move themselves;
36 9      |    follows behind. Even jumping animals all make a flexion in the

40 15     |        so are the fins in water animals, and the feather-like wings
