This is a newly hatched juvenile Eumicrotremus awae lumpsucker, a species found along the Pacific coast of Japan's main island of Honshu. The fish is 2mm to 3mm in size, perched on brown algae (Lessoniaceae). The juveniles retain this distinct pattern with white rings for a brief time, eventually taking on solid coloration that varies from brown and red to green, pink and other hues.
