Famed marine researcher and illustrator Richard Ellis brings us a work of scientific achievement that will forever change the way we think about fish, fishing, and the dangers inherent in the seafood we eat. The bluefin tuna is one of the world's biggest, fastest, and most highly evolved marine animals, as well as one of its most popular delicacies. Now, however, it hovers on the brink of extinction. Here Ellis explains how a fish that was once able to thrive has become a commodityand how the natural world and the global economy converge on our plates. With updated information on mercury levels in tuna, this is at once an astounding ode to one of nature's greatest marvels and a serious examination of a creature and world at risk.From the Trade Paperback edition.
