Self-described as half-teacher, half-naturalist, Dr. Kenneth S. Norris is one of the world s foremost authorities on whales and dolphins, those most appealing creatures with whom we share the planet. Focusing on the spinner dolphins off Hawaii, Norris carries us through his earliest contacts with these graceful animals (including work with Gregory Bateson), his attempts with teams of students to learn about their complex lives in the sea, and finally to the tragic dolphin kill in the yellowfin tuna industry.".
