(hermanusbackpackers) Sharks do not have bones. Instead, their "bones" are made of cartilage. Cartilage is like a soft bone. It is the same stuff that you find in your ear or the tip of your nose. Bones are heavy and they do not float.

Great white sharks are large sharks that roam the oceans. They have been named great whites because they are big, and because they have a white stomach. Their back is grey. Most sharks, and many other fish, have a stomach that is lighter than their back. That helps them to blend into the ocean. If a predator is looking down on them from above, their darker side blends in with the ocean bottom. If a predator is looking at them from below, their lighter side blends into to lighter shade at the top of the water. Scientists have begun to study these amazing animals more and more. Here are some fun facts they have found out about the great white shark. How much do you know about these wonderful marine animals? Can you answer these questions? What two things make great white sharks float? How many teeth can a great white have in their lifetime? How many great whites do humans kill each year? How do great whites warm themselves? How long is a great white's brain? Find out more about great white sharks and amaze your family and friends with these fun facts.

Answering every conceivable question about sharks, authors Gene Helfman and George H. Burgess describe the fascinating biology, behavior, diversity (there are more than 1,000 species worldwide), and cultural importance of sharks, their close relationship to skates and rays, and their critical role in healthy ecosystems. Helfman and Burgess take readers on a round-the-world tour of shark habitats, which include oceans as well as lakes and even rivers (as far up the Mississippi as St. Louis). They describe huge, ferocious predators like (Great) White and Tiger sharks and species such as Basking and Whale sharks that feed on microscopic prey yet can grow to lengths of more than 40 feet. The mysterious and powerful Greenland shark, the authors explain, reaches a weight of 2,200 pounds on a diet of seal flesh. Small (less than 2-foot long) Cookiecutter sharks attack other sharks and even take a chunk out of the occasional swimmer. Despite our natural fascination with sharks, we have become their worst enemy. Many shark species are in serious decline and a number are threatened with extinction as a result of overfishing and persecution. Sharks: The Animal Answer Guide presents a perfect mix of current science, history, anthropology, intriguing facts, and gripping photographs. Whether your fascination with sharks stems from fear or curiosity, your knowledge of these animals will improve immensely when you consult this book.

"Christopher Wanjek uses a take-no-prisoners approach in debunkingthe outrageous nonsense being heaped on a gullible public in thename of science and medicine. Wanjek writes with clarity, humor,and humanity, and simultaneously informs and entertains." -Dr. Michael Shermer, Publisher, Skeptic magazine; monthlycolumnist, Scientific American; author of Why People Believe WeirdThings Prehistoric humans believed cedar ashes and incantations could curea head injury. Ancient Egyptians believed the heart was the centerof thought, the liver produced blood, and the brain cooled thebody. The ancient Greek physician Hippocrates was a big fan ofbloodletting. Today, we are still plagued by countless medicalmyths and misconceptions. Bad Medicine sets the record straight bydebunking widely held yet incorrect notions of how the body works,from cold cures to vaccination fears. Clear, accessible, and highly entertaining, Bad Medicine dispelssuch medical convictions as: * You only use 10% of your brain: CAT, PET, and MRI scans all provethat there are no inactive regions of the brain . . . not evenduring sleep. * Sitting too close to the TV causes nearsightedness: Your motherwas wrong. Most likely, an already nearsighted child sits close tosee better. * Eating junk food will make your face break out: Acne is caused bydead skin cells, hormones, and bacteria, not from a pizza witheverything on it. * If you don't dress warmly, you'll catch a cold: Cold viruses arethe true and only cause of colds. Protect yourself and the ones you love from bad medicine-the brainyou save may be your own.
