 AO series separated by no more than their diameters, usually less. FLO about its diameter 

 behind a vertical from origin of pectoral fin and variably above that origin by 33% (26-39% of 

 the distance from it to lateral line. VLO over bases of inner pelvic rays and about 46% (41-52%) 

 of the distance from them to lateral line. SAO.,, Pol, and Prcj below lateral line by about two of
