Butterfishes, white pomfrets or silver pomfrets are the members of the Stromateidae family. They are found in north and south America, western Africa, and Indo-Pacific oceans. Butterfishes are recognized by their deep body, small eye, silvery, pale or bluish body colour, no keels or scutes near caudal-fin base, and no pelvic fins.
Butterfishes are primarily coastal fishes occurring in large schools mainly in depths shallower than 100 m. They feed mainly on zooplankton, particularly copepods and decapod larvae.
There are 3 genera and about 16 species of Stromateidae worldwide. Malaysia has only one genus and 2 species.
