Hello how may I help you? Can you look up a record for me? Yes, I can. I gotta know what the biggest snake ever recorded was? Do you mean the biggest type of snake, or the biggest individual snake ever? The biggest individual snake ever recorded. The biggest ever snake is a reticulated python named Medusa, length of 25 feet, 2 inches. That is one big snake. Do you know if that type is poisonous? I don't believe so. That's good, but I would still hate to run into one of those. Thanks for the info. You are welcome. Stay away from those mega snakes!
