[单项选择]Children’s stories such as" Little Red Riding Hood" and "The Three Little Pigs" have depicted wolves. as frightening animals. In reality, these animals are social, nurturing creatures. They often spend the better part of their day playing with and tending to their young.
There are two recognized species of wolves: the gray wolf and the red wolf. The grey wolf, is the largest member of the wolf family.
The grey wolf had one of the widest distributions of all mammals on the planet. It once roamed North America, Europe, and Asia, but years of persecution have reduced its numbers significantly, especially in Europe.
In Alaska, the northwest territories, and the former Soviet Union, the grey wolf has a thriving population. In the Northwest United States, however, the grey wolf is almost extinct, with a population of perhaps 30. Farther south in the United States the grey has disappeared completely. In Mexico, researchers estimated that fewer than 10 greys survive.
