A total of 73 small juveniles (46.0-115.2 mm folk length) of the genus Beryx were caught by a large mid-water trawl performed in the West Mariana Ridge, western North Pacific in 2013. Mitochondrial DNA sequence (COI gene) analysis performed on 66 individuals revealed that all individuals were Beryx mollis. Oval posterior nostril, a characteristic of B. mollis, was confirmed to be valid in these small juveniles. These juveniles appeared to be captured in epipelagic zone. This is the first report that many small juveniles of B. mollis were caught.
