Do Bothans make a physical appearance in Star Wars?

A haunting quote from Star Wars: Return of the Jedi is

"Many Bothans died to bring us this information."

I love how the actress looks as she delivers this line, as if she is remembering specific individuals that were lost. From what I can remember, this is the only mention of Bothans. I have only watched the films, so I don't know anything about their race beyond this quote. Do Bothans appear anywhere in the Star Wars films? Are they depicted in any group shots?
