Whale Vassili Papastavrou
Published by Dorling Kindersley, 1993.
Scientists believe that the mighty whale, the largest creature on Earth, evolved from a much smaller, hoofed animal that lived on land. Today, whales are found in every ocean from the tropics to the Arctic. They are even found in five of the world's rivers. This book explores the different kinds of whales, the way they court each other and give birth, their skeleton and body structure, and the way they communicate. You'll also find information about whale relativeswalruses, seals, dolphins, and dugongs. Large color photographs and drawings focus on such topics as the whale's evolution, the whale in the wild, and the whale's skeleton. There are also sections that show some products made from whales, the myths and legends concerning these creatures, whale hunting, whale watching, and the efforts to save the whale from extinction.
A Whale Biologist at Work Sneed B. Collard, III
Published by Franklin Watts/Scholastic, 2000.
Would you like to study whales? Meet a marine biologist who studies whales off the coast of California, where almost half of the blue whales in the world swim. Learn how can you identify individual whales. Explore numbers, migration patterns, and behaviors of blue whales and humpback whales. Find out about the world's largest animal. Observe whales spy-hopping, breaching, and playing in the ocean. Examine why whales are in danger and learn what people are doing to help them.
Watching Whales John F. Waters
Published by Cobblehill Books/Penguin Putnam, 1991.
A blue whale grows to be 100 feet long and can weigh 160 tons. Although whales are the world's largest animals, they are gentle and graceful, as the fifth graders in this book find out. After learning about whales and participating in a whale adoption program, they take a whale-watching trip. They see whales jump completely out of the water and land with a huge splash. They watch as a newborn humpback waves its flipper, and they learn how their adopted whale, Salt, is faring. This exciting chronicle of a whale-watching trip contains color photographs and gives information about whale watching and whale adoption programs.
