paedogenesis Reproduction by an animal that is still in the larval or pre-adult form. Paedogenesis is a form of neoteny and is particularly marked in the axolotl, a larval form of the salamander, which retains its larval features owing to a thyroid deficiency but can breed, producing individuals like itself. If the thyroid hormone thyroxine is given, metamorphosis occurs.
