Hello how may I help you? Hi! Do you need help with something? How big was the biggest snake ever? The largest snake recorded was around 50ft long and around 26 in. in width. Was it a python? Yes it was. Did someone find it or did they raise it? It was found in the Amazon river wandering around looking for prey. Scary. What kind of venom does one of those snake have Fortunately, they are non venomous. However, Their bites may cause infections if left untreated. That's good to know. Thanks for the info You're welcome!
