Scales ctenoid;  lateral line midlaterally on side. 
Two dorsal fins, first with moderately elongate base, centred on body, supported by rays with second or third longest, second ray in adult males exceptionally long; second dorsal small, adipose; anal fin long-based, originating slightly behind posterior end of first dorsal; caudal fin forked.
