Descended from enormous prehistoric creatures, sea turtles are fascinating. Hatched from eggs smaller than a baseball, some can grow to weigh over a thousand pounds. Once adults, they can live to be around 100 years old. And when it's time to nest, they migrate more than 1,000 miles. With colorful, clear illustrations and straightforward text, Gail Gibbons introduces the eight kinds of sea turtles living in the ocean today. Learn to tell the difference between sea and land turtles with labeled diagrams, and experience the hatching of the tiny turtle babies with detailed illustrations. Expertly vetted, this updated edition now includes up-to-date information about these popular reptiles. Sea Turtles also gives young readers an accessible overview of how the lives of these large reptiles have become threatened and discusses the conservation efforts currently taking place. Ideal for aspiring oceanographers, this brightly-illustrated book is a perfect introduction to the subject.
