For a better understanding of this unpredictable killer of the sea, Thomas Helm tells the complete story of the shark, giving his origin, history and descriptions of the most important species. Dramatic accounts of shark attacks shed true light on his real danger, and studies of prevention and repellents show how tragedy may be averted. The author describes game and commercial shark fishing, in which he has participated. He discusses other bad actors of the deep, moray eels, octopuses, stingrays, etc. as well as the barracuda, whose assaults are often attributed to sharks, and the porpoise, the natural enemy of the shark. From his own expierence, love of adventure, and a narrative sense that distinguished his previous book, Helm gives a thrilling and informative account of a creature which has long inspired awe and captured the imagination of mankind.
