Hello how may I help you? I want to find what the biggest snake ever was. Do you mean biggest individual snake, or largest type of snake? The biggest snake ever recorded and it's species name. The largest ever snake was a reticulated python named Medusa with a length of 7.67 meters. What about the biggest alligator? I'm sorry, I don't have that information. What was the second largest snake? I don't know that either, I'm afraid. That's okay, thanks for the help. You are welcome. Have a good day.
