Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 10; Vertebrae: 26. This species is distinguished by the following characters: preopercular canal with 3 pores and 2 pores over opercle; color in life translucent with yellow markings on the body and fins, with a distinctive dense black oval blotch posteriorly on first dorsal fin; 5th -8th caudal fin rays usually elongate and filamentous, extending beyond other rays; branchiostegal membranes with one cycloid scale on each side; second dorsal fin I, 9; anal fins I, 10; pectoral fin rays 20-21 (Ref. 58420).
Specimens trawled from muddy substrate (Ref. 58420).
