 | | Neoteny, sometimes called paedomophism, is apparent in all caudate families except Rhyacotritonidae. |
 | | Facultative neoteny is observed in Salamandridae, Dicamptodontidae, Ambystomatidae, Hynobiidae, and Plethodontidae. |
 | | In the case of facultative neoteny, genetics may play a role in the individuals predisposition and affinity for neoteny, however, the cause of neoteny is based on environmental conditions, such that a permanently aquatic lifestyle would benefit the individual. |
