Description
Sharks are in trouble.
Fifty shark species are at high risk of extinction, and another sixty-three are threatened. These intelligent, mysterious--and sometimes scary--fish evolved about 420 million years ago. They have adapted to survive deep in the ocean and in shallow-water habitats. Commercial fishing and finning are threatening shark populations. So is water pollution. Marine biologists and others, including young people, are working together to save these fascinating predators.
Discover the work of scientists and conservationists as they study shark biology and morphology; research migration, feeding, and mating patterns; delve into human, climate, and other threats to shark habitat; and develop sophisticated technologies to aid sharks and shark research. See how scientists also educate the public about real and imagined fear of sharks and encourage citizen participation in shark conservation efforts. Learn about high-tech tagging for tracking shark migration paths. Discover the autonomous underwater vehicles and drones that divers use to observe and photograph sharks up close. Visit shark sanctuaries in the South Pacific Ocean. You'll even meet the Shark Lady, a.k.a. Eugenie Clark, a pioneer ichthyologist (shark scientist). Through research and advocacy, people around the world are working to protect--and admire--sharks.
"[A]n engaging, well-researched book about a much maligned species of fish that deserves our protection."--Booklist
"A remarkably thorough tour of the world of sharks and marine scientists' efforts to educate the public about our ocean's apex predators."--Kirkus Reviews
