African Wild Dogs

These dogs are really cool. But also endangered. I'm not sure if there is a cool animal that isn't.

Their hunting methods are like a coordinated dance, each dog knows what it's job is and relies on the others in the pack to get their jobs done as well. If you're interested, check out this Wikipedia article. The BBC series "Planet Earth" also covered the African wild dog. There are also a few pretty good videos of them on YouTube.
