Mexican gray wolves are believed to be extinct in the wild, which means that the only remaining ones live in zoos or wildlife centers. These three eight-week-old pups were part of a litter of eight born at a zoo in Wichita, Kansas. Young wolves spent a lot of time attacking and wrestling each other playfully, helping them learn hunting skills that they'll need later on. -

Wolves live in packs of about six animals, which are usually related. The wolves do everything together—hunting, sleeping, eating, even playing, like these two gray wolves are doing in Ely, Minnesota. -

This gray wolf is just a blur as he runs through Yellowstone National Park in Wyoming. When they are hunting with their packs, wolves set out at a smooth, easy trot. They can lope along for many miles, running quickly for short distances. They usually travel in single file. -

The wolf is the largest member of the dog family. With thick, shaggy hair and a bushy tail, it looks a lot like a German shepherd dog. Wolves have long legs to run great distances and powerful jaws to grab prey and hold it. The gray wolf pictured here lives at the International Wolf Center in Ely, Minnesota. -

When a wolf throws his head back and howls, like these gray wolves in Idaho's Sawtooth Mountains are doing, he's communicating with his packmates. Wolves may howl at any time of the day or night, and once one wolf starts, others may join in.
