What python is poisonous?
As far as I know there are few poisonous snakes here, tree snakes specific but no more venom than it takes to stun a small bird or rat. Nothing here could cause any human any problem, you would get more of an ache from scorpion stings here, which are just like harsh bee stings but people do often have slight reaction and can swell a little of last a few days, week maybe.
I would be surprised if all snakes found here were not killed, even old specimens as in the photo, maybe 40-50 year old, older even depending on species. Ignorance is an excuse to a certain degree when it comes to killing wildlife, lack of education on how important every species is, from plants to flies is terrible in a country that at one time much have been richer at least in more huntable species, but us from well educated countries have no excuse at all, other than simply don't care, and I do know a few expats in that mindset. I see schools educating kids in this area now so maybe things may improve. I think once the overall level of education here has stepped up a notch everything will improve, including the micro environment around our landscapes.
