Sharks

The mere glimpse of a SHARK in the water is enough to arouse fear and panic in most onlookers. The gaping jaws, rows of sharp teeth, and the triangular fin slicing through water are familiar characteristics of the shark family. What is it about sharks that causes this feeling of terror? Are they all killers, intent on hunting about their victims--especially human ones--or is there more to the life of a shark than just hunting its prey? Well over 350 species of sharks are known to science, and they can be found in all the world's oceans, from the polar regions to the equator, and at all depths, from the surface and the seashore to the deepest ocean troughs. Some live in estuarine conditions, finding their way into river mouths, and one or two species are able to live in fresh water in large river systems. Given their abundance and sheer variety, sharks bear closer examination--and this book gives readers the chance to meet these fascinating creatures face to face. Illuminating in both words and remarkable pictures, SHARKS is just one title in the acclaimed Creatures of the Ocean series. For those who want to delve into the amazing and sometimes mysterious world of ocean life, these books are a wonderful resource filled with scientific fact and beautiful photography.
