Su questo libro

Dalla quarta di copertina:

Sharks and their kin - skates and rays - have remained essentially the same for hundreds of millions of years. Now their existence is threatened by man - through overharvesting and misunderstanding.Thomas Allen examines the behavior, appearance, size, and distribution of over one hundred ancient and fascinating shark species. He also provides scientific explanations for their evolution, debunks the sometimes bizarre and amusing mythology surrounding sharks, and describes the commercial uses that make these species invaluable to humankind, as well as the abuses that have endangered their survival. The Shark Almanac offers the most up-to-date information on sharks, including recent studies on shark cartilage in cancer research, current populations finds of various species, shark attacks - where and how they happen, and what can be learned from them in order to avoid becoming a victim - and the ongoing conservation efforts to ensure the survival of sharks around the world. (81/4 X 101/4, 300 pages, color photos, b&w photos, illustrations, tables)
