Dr. Sampson, the Paleontologist: Oh, it's heading for the Thames. They always made for the freshwater rivers to die. That's where their skeletons have been found - some irrestible instinct to die in the shallows that gave them birth. You know, all my life I hoped this would happen. Ever since childhood I expected it. I knew these creatures were alive somewhere, but I had no proof, scientific proof, and I had to keep it to myself, or my colleagues would have all laughed at me. See, no form of life ceases abruptly, and all those reports of sea serpents - well, what can they be?... The tall, graceful neck of paleosaurus. He can stay underneath the surface for an age, and now he comes to the top.

Steve Karnes: I feel Admiral, what we're facing is a marine animal of tremendous size and strength.

Professor James Bickford: Behemoth?
Steve Karnes: That's as good a name as any for now.
