The coloration of small individuals of Nozawa's prickleback, Stichaeus nozawae is presented for the first time, based on a specimen (112 mm SL) collected by T/S Ushiomaru from the Funka Bay, Hokkaido. The specimen has obscure bands on dorsal, anal, caudal and pectoral fins. Although specimens of comparable sizes (57.4 -168 mm SL) have obscure bands on these fins, most larger specimens (252 -361 mm SL) have no bands on the caudal and pectoral fins. Most descriptions or images in previous
more » ... including the original description, were based on large specimens (220 -450 mm SL), which have no bands on these fins. Thus, bands on caudal and pectoral fins of S. nozawae tend to disappear with growth.
