The larva can look completely different from the adult form, for example, a [[caterpillar]] differs from a [[butterfly]]. Larvae often have special (''larval'') organs which do not occur in the adult form. The larvae of some species can become [[puberty|pubescent]] and not further develop into the adult form (for example, in some [[newt]]s). This is a type of [[neoteny]]. It is a misunderstanding that the larval form always [[ontogeny recapitulates phylogeny|reflects the group's evolutionary history]]. It could be the case, but often the larval stage has evolved secondarily, as in insects. In these cases the larval form might differ more from the group's common origin than the adult form. The early life stages of most [[fish]] species are considerably different from juveniles and adults of their species and are called ''larvae''.
