Larvae and eggs are developmental forms of what?

Larvae and eggs are developmental forms of many organisms, particularly invertebrates, amphibians, and some fish. These stages represent early life forms that undergo significant changes as they mature into adults through processes such as metamorphosis. For example, in insects, the larval stage often differs greatly in form and function from the adult stage. In amphibians like frogs, eggs hatch into larvae (tadpoles) that eventually transform into adult frogs.
