But to continue our overview: the remainder of book II (from chapter 5 on) discusses the causes of the embryological development of vivipara, while the ovipara are the primary focus in book III, which closes with a discussion of animals that are not sexually generated, including those that arise ˜spontaneously.™
Some of these are called membranes and others choria, the difference being one of more or less, and they exist in ovipara and vivipara alike.
The passage is the same as that of the solid nutriment in all those animals that have no penis, in all the ovipara, even those of them that have a bladder, as the tortoises.
But nevertheless they are found to wake even in the womb (this is clear in dissections and in the ovipara), and then they immediately fall into a sleep again.
Therefore in such animals the uterus is dissimilar to that of both the vivipara and ovipara, because they participate in both classes; for it is at once near the hypozoma and also stretching along downwards in all the cartilaginous fishes.
For no viviparous animal, be it apodous or be it possessed of feet, is so given to creep into holes as are the ovipara.
In the vivipara it is large and rich in blood, because of their natural heat; while in the ovipara it is small and dry but capable of expanding to a vast extent when inflated.
In the ovipara, again, it is low in fish (as in women and the viviparous quadrupeds), high in birds and all oviparous quadrupeds.
They exist in none but viviparous animals; though in some ovipara certain parts are metaphorically spoken of as horns, in virtue of a certain resemblance.
But among the ovipara (1) birds produce a perfect hard-shelled egg, unless it be injured by disease, and the eggs of birds are all two-coloured.
