Short description
Identification keys | Morphology | Morphometrics
This species is distinguished by having the following characters: anal fin rays 12-13; second dorsal fin rays, 13-14; first dorsal fin with second spine elongate and filamentous in both sexes, the second dorsal fin with no filaments in males; male body colour pattern dorsally with 3 pairs of vertical dark brown streaks, followed by a single saddle below the end of the second dorsal fin and on the caudal peduncle (Ref. 84091).
Specimen was collected with a beam trawl, probably on soft bottom for species of Centrodraco usually occur on patches of soft substrate on the continental slope. Extremely rare in collections, and probably also biologically rare (Ref. 84091).
