A deformed individual of the spotted parrot fish Oplegnathus punctatus, lacking the caudal fin, was caught by a set-net off Obama, Wakasa Bay in the Sea of Japan, on September 25, 1995. An X-ray photograph indicated that the specimen was missing the last two and half centra together with the entire caudal skeleton. The surface of cut-end was healed and covered with skin. The posterior parts of dorsal and anal fins were elongated vertically.
