Other editions of book Sharks

Are sharks really dangerous? How many kinds are there? And how do they help the environment?From huge whale sharks to tiny dwarf sharks, this book has everything you need to know about one of our most popular--and mysterious--sea creatures. Millions of years before the first dinosaurs walked the earth, the first sharks swam in the sea. Though they're often feared and misunderstood, most sharks aren't dangerous to humans.With her signature combination of accessible, kid-friendly text and clear, well-labeled illustrations, Gail Gibbons introduces many of the more than three hundred types of sharks in the ocean, and gives concise information about their habitats and physical characteristics.

Sharks first lived more than 400 million years ago, 200 million years before dinosaurs walked the earth. From the dwarf shark to the great white shark, here is information on the physical characteristics of these animals, how they differ from other fish, how they are born (some hatch from eggs, others are born alive), and how they survive in their environment. Their role in ocean life and how their survival is threatened is also discussed.
