Review # 1 was written on 2012-10-01 00:00:00 Brandie Fowler Sperm whales are the largest toothed predators on the planet. Their teeth are 10 inches long and they only have them on their lower jaw (40 ish of them). Their blowholes are "s" shaped. Males stop growing when they are 50 years old. Females stop when they are 30. The 2 genders swim in separate pods--the largest and oldest males swim alone. Giant squid have eyes the size of dinner plates (the largest on the planet).

Review # 2 was written on 2018-10-21 00:00:00 Stephen Galat There are many migratory species, with one of them including sperm whales. The book discusses the massive size of sperm whales with regard to their weight, length, and features (brain, heart, flippers, etc.). It also provides information on how the whales migrate, where they migrate, and when they do it. These whales feed on their favorite food- squid, but also on octopus, shark, and fish. Sometimes the giant squids become their biggest enemy, ranging up to 30 feet in length. The book ends with some information on how sperm whales communicate, predators they face, and the dangers of pollution to these mammals. A list of organizations that help sperm whales or other animals is provided. I thought that this book provided solid information on sperm whales. However, the title was a little misleading. Just from the title, I assumed that the book would cover information on several types of whales, not just one. With that being said, the book was able to give more detailed information on sperm whales, helping me get a better understanding of them. The copyright page indicated that this book was published by the National Geographic Society. The National Geographic Society is a nonprofit organization with researchers who collect data and then publish the information to the public. This ensures that the book is informational and nonfiction. This book contains many signature text features of informational books including a table of contents, glossary, index, pictures with captions, and headings. All of these help the reader to find specific terms or subjects easier. For example, the table of contents provides page numbers for the different subsections in the book so they can flip straight to the correct page. Overall, I really enjoyed this book and would recommend it to anyone interested in whales!
