Yes, Even Crocodiles Go Through Puberty

Yes, Even Crocodiles Go Through Puberty


1. Little is known of its timing or process of puberty in crocodylians.
2. Researchers looked at snout-vent length, body condition index, and teeth of Morelet's crocodile (Crocodylus moreletii) and found distinct differences between males and females, thus marking a sexual dimorphism that begins to present with the onset of puberty.
3. This bodily manifestation of puberty is a novel observation for crocodylians and lays a foundation for further study among species of how changing endocrine signaling within sexually maturing males may also influence a broader range of secondary sex characteristics.
