Sharks hold a unique place in the sea kingdom. Among fishes they are the oldest inhabi-
tants of the hydrosphere. Their tribe includes the largest fishes in the world, as well as
those most dangerous to man. Because sharks are so fascinating and dangerous, they are
the target of intense scientific study. More than two hundred scientists around the world
are working to learn their secrets and to predict their moods. Cautious by nature, the sleek
and efficient creatures usually avoid clumsy human intruders, but occasionally they attack
with ferocity. Scientists want to know why, not only for their own information but also for
the safety of swimmers, divers, and sailors all over the globe.
This is a book to bring you up to date on shark knowledge, fact by fact.
