The Megalodon (i.e. Carcharodon megalodon, the great-great white shark) was once the most fearsome predator of the sea, but is now pretty much relegated to paleontology and so-bad-it-sailed-past-good-into-really-bad movie territory. If it were alive today, would it be terrorizing the high seas, or would it be fetching $600,000 per dorsal fin on the shark-fin soup market?
Some scientists, when called upon by nerds to offer a scientific take on B-movies, believe it is the latter.
