A concise introduction to some of the oldest living animals. Descended from enormous prehistoric creatures, huge sea turtles are fascinating creatures. Hatched from small eggs, some can grow to weigh over a thousand pounds. With colorful, clear illustrations and simple text, Gail Gibbons introduces the eight kinds of sea turtles living in the ocean today. Their similarities and general features are introduced with labeled diagrams, and the differences between species are clearly explained. Sea Turtles gives young readers an accessible overview of how populations 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.
