Another day of moving some giant snakes😅 These two females actually came from the same clutch but one has grown a lot more in the same time period🤯 Reticulated pythons grow the fastest during the first two years of life but don’t ever stop growing😳 Their growth rate does significantly slow down over time and they reach their full length at about 4 to 5 years🙌
