Morphology | Morphometrics
soft rays: 8. This species is distinguished from congeners by the following set of characters: cephalic sensory-pore system lacking all pores 98% of the time; dorsal/anal fin-ray formula 8/8; pectoral-fin rays 15-16, ventralmost two rays unbranched with at least 2 (but up to 4) lower rays branched at tips above this, remainder of rays unbranched; 4th pelvic-fin ray bifurcated with each branch about 60% of total length of the ray; unbranched 5th pelvic-fin ray 13-20% of 4th; non-filamentous dorsal-fin spines, tubular anterior nares short, less than ½ pupil diameter in length; when alive, body is translucent and crossed by five broad orange to red bands (Ref. 82345).
