when the young animal hatches out of the enve-lope or the mother gives birth. In the majority of animals, development occurs in the so called indirect fashion: embryogenesis results in a first phenotype, the larva. An example is the sea urchin, which can be taken as prototype of animal developments (Fig. 4.2). The larva itself
