Description
Preface Amazing Sharks: Sharks have been living for over 400 million years. They came through the five great mass extinctions, and competed favorably with the rapidly evolving bony fishes, and today they are among the top predators in the sea. During all that time, sharks have been honed to evolutionary perfection, with a body that yacht and submarine designers can only envy and with wide-ranging sensory systems that military technologists would die for. The archetypal shark is a sleek, torpedo-shaped hunter with a tall, triangular dorsal fin and powerful scythe-shaped tail, but this is only one of many types of shark.
