neoteny Attainment of sexual maturity during the larval stage. Neoteny is evident in the retention of gills, as in some salamanders, the best known example of which is the axolotl of the western United States and Mexico. An entire order of tunicates (sea squirts), the Larvacea, is permanently larval, never reaching a typical adult form.
