What is a bison also known as?

A bison is also known as a buffalo. However, it's important to note that "buffalo" can be a bit confusing, as it's also used to refer to different animals in Africa and Asia.

* American Bison: The species found in North America is called American bison or American buffalo.

* European Bison: The species found in Europe is called European bison, European wood bison, or wisent.

* Water Buffalo: This is a completely different species of buffalo found in Asia and Africa.

So, while "buffalo" is a common name for bison, it's more accurate to call them American bison or European bison to avoid confusion.
