I don't have enough data to give a clear answer on those topics. There is an extreme size difference in southerns from what I have seen in captivity. And the largest eastern male I have seen was about 300 grams. (Tiny compared with the giant females out there) I'm sorry, I can't answer this question with any certainty because of my lack of data/experience. You might try researching mark and re-capture data from published works. You want a source or sources who have processed dozens, even hundreds of specimens before you will get a good idea. Let me know what you find out!
