We know less about the ocean floor than we do about the moon, says Sweeney, but we do know that ""in these black cold depths of unbearable pressures swim many forms of animal life--all savage, grotesque. . . brutal, aggressive, and monstrous."" And who can say that no surviving dinosaurs are hiding there as well? Sweeney quotes an odd lot of experts to the effect that marine mutations are more common than those of barnyard animals--and how do we know that chemicals dumped into the sea are not creating horrible sea monsters? Sweeney cites the discovery of the living coelacanth as well as less well documented sightings from ancient times on; he, for one, seems to find their sheer number and coincidence tantamount to proof of something or other. Most recently, a 1973 ship's crew tangled with what has been diagnosed as a giant lion's mane jellyfish; divers for gold have encountered pig-like aggressors and twelve-inch eyes; and Nessie has proven very clever at thwarting scientific investigators though all agree that ""there is something there."" Holy sea cow, kids!
