=== Larval and juvenile phases ===
In most species, the young organism that is just born or hatched is not sexually mature yet and in most animals, this young organism looks quite different than the adult form.<ref name="Gilbert-2000-2">{{cite book |last1=Gilbert |first1=Scott F. |title=Developmental Biology |edition=6th |date=2000 |publisher=Sinauer Associates |chapter-url=https://www.ncbi.nlm.nih.gov/books/NBK9981/ |chapter=The Circle of Life: The Stages of Animal Development }}</ref> This young organism is the larva and is the intermediate form before [[Metamorphosis|metamorphosing]] into an adult.<ref>{{Cite web |title=larva {{!}} Definition, Forms, & Facts {{!}} Britannica |url=https://www.britannica.com/science/larva |access-date=2022-04-25 |website=www.britannica.com |language=en}}</ref><ref name="Gilbert-2015" />  A well known example of a larval form of an animal is the [[caterpillar]] of [[Butterfly|butterflies]] and [[moth]]s.  Caterpillars keep growing and feeding in order for enough energy during the pupal stage, when necessary body parts for [[metamorphosis]] are grown.<ref>{{Cite web |title=Butterfly Life Cycle |url=https://ansp.org/exhibits/online-exhibits/butterflies/lifecycle/ |access-date=2022-04-26 |website=ansp.org |date=14 September 2020 |language=en}}</ref>  The juvenile phase is different in plants and animals, but in plants juvenility is an early phase of plant growth in which plants can't flower.<ref>{{cite book |doi=10.1016/B978-0-12-394807-6.00105-2 |chapter=Juvenility |title=Encyclopedia of Applied Plant Sciences |date=2017 |last1=Sgamma |first1=T. |pages=437–441 |isbn=978-0-12-394808-3 }}</ref>  In animals, the juvenile stage is most commonly found in social mammals, such as [[Dingo|wild dogs]], [[monkey]]s, [[ape]]s, [[lion]]s, [[Wolf|wolves]], and more.  In humans, [[puberty]] marks the end of this stage and [[adolescence]] follows.  Some species begin puberty and reproduction before the juvenile stage is over, such as in female non-human primates.<ref>{{Cite web |title=Juvenile Stage {{!}} Center for Academic Research and Training in Anthropogeny (CARTA) |url=https://carta.anthropogeny.org/moca/topics/juvenile-stage |access-date=2022-04-25 |website=carta.anthropogeny.org}}</ref>  The larval and pupal stages can be seen in the figure to the right.
