Histories

The Arabians also say that the whole country would be full of these snakes if the same thing did not occur among them that I believe occurs among vipers.

Somehow the forethought of God (just as is reasonable) being wise has made all creatures prolific that are timid and edible, so that they do not become extinct through being eaten, whereas few young are born to hardy and vexatious creatures.

On the one hand, because the hare is hunted by every beast and bird and man, therefore it is quite prolific; alone of all creatures it conceives during pregnancy; some of the unborn young are hairy, some still naked, some are still forming in the womb while others are just conceived.

On the one hand there is this sort of thing, but on the other hand the lioness, that is so powerful and so bold, once in her life bears one cub; for in the act of bearing she casts her uterus out with her cub. The explanation of this is that when the cub first begins to stir in the mother, its claws, much sharper than those of any other creature, tear the uterus, and the more it grows the more it scratches and tears, so that when the hour of birth is near seldom is any of the uterus left intact.
