Three juvenile specimens of Odontanthias borbonius were collected from Suruga Bay (2 specimens, 20.0–23.4 mm standard length (SL), 95–100 m depth) and Okinawa (23.7 mm SL, 180 m depth), Japan. Because little is known of juvenile morphology of the species, the specimens are described and compared with adults from Japan. Fresh coloration of the juveniles was similar to that of adults, being characterized by a pale pink body and large yellow spots. Following fixation, the juvenile coloration was lost, although black pigment vesicles scattered in the former positions of the yellow spots indicated that O. borbonius can be distinguished from all other congeners, which lack such spots. Juveniles of the former had a large, smooth, interopercular spine, the supraocular ridge with serrations, and serrated posttemporal spines.
