What is mean by wildlife?

Wildlife can be associated with animals in the jungle, or wilderness; untamed animals; or it can be used as an expression when a person is out of control. Or it can be used in the sense that you're out in the open, or that you're out on your own. Such as; I'm living the wildlife of the jungles of Africa; or, Wow, I'm finally on my own, living the wildlife! Well, Wildlife does mean the life in wilderness, but not untamed animals, rather the animals (or any organism) that is not domesticated for human use or fun. For example if a circus worker tamed a lion, it will still remain a wild animal. But those organisms that are tamed and harnessed for years are not wild anymore. That's why some of them are not found in wild at all (perhaps it is speciation by Isolation). That's what biologist mean by wildlife. Hope you get your answer. Have a great time and fun with wildlife.
