These four companion books take a dramatic look at our watery planet. For centuries, killer whales had a fearsome reputation as indiscriminate killers. In recent years we have realized that they are incredibly complex, endearing, and enigmatic creatures and do not deserve their killer name. We do not understand why, but unlike lions, tigers, and polar bears, they seem to be very careful not to harm people. Killer whales are the largest members of the dolphin family. Living in close-knit family groups known as pods, they are unmistakable with their distinctive jet-black and brilliant white markings and the tall, triangular dorsal fins of the males. They are most common in the cooler waters of the polar regions but can be seen almost anywhere.
