Not too big to fail.
"The megalodon may have been the largest marine predator to ever live, growing up to 60 feet with teeth nearly the size of a standard sheet of paper."-----"In addition to reaching up to 60 feet, megalodons are thought to have weighed approximately 120,000 pounds or 60 tons." I guess the shark from "Jaws" wasn't so frightening after all. But I believe the ominous notes from the "Jaws" soundtrack signalling the approach of the shark would still be pertinent, if the volume were quadrupled.
