    The organism emerging from the egg or from the maternal body, apart from being incompletely developed, may have an organization more or less different from that of an adult. In some cases the difference is so great that, without knowing the origin of the eggs or without following the young through their full course of development, it would be impos...

  3. The word larva is applied to the young of certain animals that must undergo great physical changes before they become adults. A young frog hatches from the egg as a water-living tadpole and gradually becomes transformed into the air-breathing adult.

    A larva (/ ˈlɑːrvə /; pl.: larvae / ˈlɑːrviː /) is a distinct juvenile form many animals undergo before metamorphosis into their next life stage. Animals with indirect development such as insects, some arachnids, amphibians, or cnidarians typically have a larval phase of their life cycle.

  5. Animal development, the processes that lead eventually to the formation of a new animal starting from cells derived from one or more parent individuals. Development thus occurs following the process by which a new generation of organisms is produced by the parent generation.

  6. Definition. Eggs and larvae refer to the early developmental stages of many organisms, particularly in aquatic environments, where eggs are fertilized and develop into larvae before becoming adults.

  7. Jan 1, 1999 · The aquatic tadpole and the terrestrial frog are prime examples. Some species display indirect development; larvae must metamorphose to transform into, or be replaced by, adults. Larval evolution provides the key to unlocking metazoan evolution and diversification.
