Food fishes of small or moderate size, sometimes appearing in great 

 schools and of interest to anglers. Jenyns proposed the generic name 

 chiefly on scale structure. He describes the scales as having "instead 

 of the usual fan of diverging striae on their basal portions, a triangular 

 space filled up by a number of extremely fine, closely approximating 

 striae, parallel to each other, and also parallel to the basal margin, 

 which is cut quite square and entire." This led him to form the 

 name from a (without) and ptTris (flabellum., or fan).
