- n. The retention by an organism of larval or juvenile characters beyond the time characteristic of other members of the group to which it belongs. This may be partial, as in the case of some toads and frogs, whose young pass the winter in the tadpole condition, or total, as in some salamanders that retain their external gills when adult. Also neotenia.

“The neoteny issue is a pervasive cultural problem, but it applies to men and women alike in all aspects of our culture.”
“She even raised (and educated me in) the biology concept of neoteny, whereby new species begin to resemble the embryos of the animals from whence they evolved -- chihuahuas, for example, look like fetal wolves.”
“For me, he's fascinating as one of those ironic antiheroes, subverting the champion in his neoteny/effeteness, in his innocence -- everyboy rather than everyman.”
