Hello how may I help you? I was seeking information about a world record. What exactly are you looking for? What is the biggest snake ever? Do you mean it the biggest individual snake? Or the biggest type of snake? The biggest snake individual ever recorded. The biggest individual snake ever recorded was about 25 feet long. Wow. What is the biggest type of snake? The biggest type of snake is the rattle snake. Huh? Not the Anaconda? I apologize, the biggest snake by volume is the rattlesnake. Not by length.
