Adult male greens in the wild tend to run between 7 to 9 feet, and rarely over 35 lbs. I have noticed that with the better diets in captivity, adult male greens tend to run 8 to 10 feet, with some exception individuals getting well over 10 feet. To assess the weight condition of your male, it would be best to get a weight on this snake. A male of this size in good condition would weigh around 50 lbs. The creasing you are seeing could also occur on a snake of average weight.
