具体描述
"Crrrrrrr Huge, shaggy, and imposing, a grizzly bear can be a fearsome sight, especially when it rears up on its hind legs. Grizzly bears have no enemies but humans. Since grizzlies eat everything from fungi and insects to moose and caribou, it is usually other animals that must look out for them. Yet today the bears are a threatened species. Here Gail Gibbons takes a closer look at these vulnerable predators, noting fascinating facts about their habits, biology, and important place in their ecosystem. In an informative text with plenty of illustrations, diagrams, and cutaways, she reveals the intriguing lives of these imposing giants of the animal world.
