Sharks & Rays of the World

Did you know that sea turtles in the Atlantic Ocean grow to a larger size than those in the Pacific Ocean? Or that a mass nesting of sea turtles can consist of as many as half a million creatures? Did you know that sea turtles spend the majority of their time submerged? These are just a few of the interesting facts you'll find in "Sea Turtles of the World" 
Sea turtles have existed for more than 210 million years, surviving two waves of mass extinction. Unfortunately, many sea turtles are still threatened. "Sea Turtles of the World" focuses on the efforts to save these prehistoric-looking reptiles, and provides an in-depth look at their natural history. 
Join author and photographer Doug Perrine as he guides you through the fascinating life-cycle of sea turtles; from their harrowing dash from the nest to the ocean as vulnerable hatchlings through the many years spent at sea during maturation; from sexual maturity and reproduction, to migration. Perrine also describes the evolution of the sea turtle, its anatomy, what led to its endangerment, and the attempts to save it. 
Detailed descriptions of the Green Sea Turtle, Loggerhead Turtle, Hawksbill Turtle, Olive Ridley Turtle, Kemp's Ridley Turtle, Australian Flatback Turtle, and the Leatherback Turtle are included. Perrine also provides information on the best land and water spots to watch sea turtles. Incredible photography depicts sea turtles at home in their underwater environments.

Sea Turtles of the World (Worldlife Discovery Guides)

There are some 375 recognized species of sharks around the world, with exciting discoveries of new species every year. "Sharks" explores the changing times of these often misunderstood creatures. Popularly described as "killers" and "primitive," recent research reveals that they are rarely dangerous to humans and that they have evolved into sophisticated hunters, with unique adaptations to sustain them as top marine predators. "Sharks" provides the most up-to-date information on the behavior, biology, distribution, reproduction, senses, and habits of sharks. It also calls for swift and far-reaching conservation measures to secure their survival.
