What is "stromateidae"

The family Stromateidae of butterfishes contains 15 species of fish in three genera. Butterfishes live in coastal waters off the Americas, western Africa and in the Indo-Pacific.

The endemic New Zealand species Odax pullus is commonly called butterfish, but is from a separate family Odacidae. The Japanese butterfish Psenopsis anomala is from the separate family Centrolophidae.
