Paedomorphosis is the retention of ancestral juvenile characteristics into adulthood in the descendent. Paedomorphosis can occur three ways: Progenesis (early sexual maturation in an otherwise juvenile body), Neoteny (reduced rate of morphological development), and Post-displacement (delayed growth of certain structures relative to others).

幼体发育是保持祖先性状的过程，成年期只不过是一个衍生的过程，幼体个体发育可以观察到三个阶段：初期发育，幼态（形态学发育的快速表现过程），和加快取代期。

In this larval stage of jellyfish life, the planula hooks on to the bottom of a smooth rock or other structure and grows into another stage of jellyfish life, the polyp, which resembles a miniature sea anemone.

Reproduction of young during the larval or preadult stage, occurring chiefly in insects.

幼体生殖在幼虫或未成熟阶段对幼体的再生，主要发生于昆虫中

In juveniles, the structure of the tissues in the mesoyl layer were looser than the surface layer and there were more black chromatocytes in the surface layer than the mesohyl layer. The compositions of spicules were different in various stages of the sponge. There were no spicules in embryos and larvae. In juveniles, microscleres were the main components. However, megascleres of oxea and strongyle were the major types in adult.

在骨针组成方面，黑色软海绵随不同发育时期而有差异，在胚胎以及幼生阶段体内皆无骨针存在，白色及黑色幼体体内之骨针的组成为小型骨针，有oxyaster euaster及 oxyaster oxyspheraster两型，以及大型骨针尖杆体及二辐钝端骨针两型；而黑色软海绵成体的骨针组成为大型骨针，并未发现存在於幼体体内之小型骨针。
