A single female specimen (73.6 mm SL) of ghost pipefish, Solenostomus cyanopterus Bleeker, belonging to the family Solenostomidae (new Korean name: Yu-ryeong-sil-go-gi-gwa), was observed and collected in the water off Yeongdeck, East Sea of Korea. Unlike to syngnathids, solenostomids are characterized by having the brood pouch formed by pelvic fins in female and dorsal fin spines present. This species is characterized by having the deep snout, and short, deep caudal peduncle, but no cirri and striped markings. In the water, the species swims slowly head downward in pairs and looks like a drifting pieces of algae or fallen leaf. We describe this species as new to Korean fish fauna and propose its new Korean name, "Yu-ryeong-sil-go-gi".
