In amniote tetrapods, metamorphosis is absent because they develop directly into a juvenile form without undergoing the dramatic transformation seen in amphibians. Cleavage is meroblastic, which means it is partial, due to the presence of a large amount of yolk in the eggs. This is characteristic of birds and reptiles, which are amniotes.
