The Titanoboa, the largest known snake to ever exist, it’s as long as a school bus, maybe even longer, growing to an estimated 50 feet long and 3 feet wide. They can also get to n 42 feet and 49 feet long, with a mean weight of 2,500 pounds. Analysis of the jaw bones show that Titanoboa could crush its prey with a jaw force of 400 pounds per square inch. Can see in very dark places, and is pretty much bullet proof.
