The painted frogfish has the genus name ''Antennarius'' which suffixes ''-ius'' to

specific name ''pictus'' means "painted", the body being described by Shaw as being brown marked with red-margined yellowish blotches.

However, the dominant coloration goes from white to black, passing through a whole range of related nuances such as cream, pink, yellow, red, and brown, usually with circular eye spots darker than the background color and/or with saddles and blotches.
