The behaviour of the saurians seems pretty standard for reptilians. It reminds me of the komodo dragons or monitor lizards they show on nature documentaries: the young are meat if they're not careful. Maybe it's just a function of reptilian biology. Most reptiles seem to grow throughout their lives, which suggests there may be no meaningful adult/juvenile distinction for them culturally. The bigger, older, more experienced lizard is always your "adult" no matter how old you are.
