List of domesticated animals

This is a list of animals that have been domesticated by humans.

Semidomesticated, routinely captive-bred, or domestication status unclear
Due to the somewhat unclear outlines of what, precisely, constitutes domestication, there are some species that may or may not be fully domesticated. There are also species that are extensively used or kept as pets by humans, but are not significantly altered from wild-type animals. Most animals on this second table are at least somewhat altered from wild animals by their extensive interactions with humans. Many could not be released into the wild, or are in some way dependent on humans.
