Könsmognad: Lm ? range ? - ? cm
Max length : 69.0 cm TL hane/ej könsbestämd; (Ref. 3055); publicerad maxvikt: 2.1 kg (Ref. 3013)
Taggstrålar i ryggfenan (totalt) : 1; Mjukstrålar i ryggfenan (totalt) : 10 - 11; Mjukstrålar i analfenan: 12 - 13. Diagnosis: body rather elongate, 6 times longer than deep; occipital process 3-5 times longer than broad (Ref. 57125). 10-11 branched dorsal-fin rays (Ref. 57125), 1st extended into long filament, following into shorter ones (Ref. 7324, 31256, 57125). Longest filament comprised 2 to 3 times in standard length (Ref. 3036, 57125). Predorsal length comprised 2.6 to 2.9 times in standard length; head width 1.6-1.9 times in head length; width of premaxillary tooth plate 2.4-2.8 times in head length; upper caudal-fin lobe often prolonged into a short filament (Ref. 7324, 57125). Upper caudal-fin lobe comprised 2.5 to 3.5 times in standard length (Ref. 57125).
Body shape (shape guide): elongated.
