Abstract

A specimen (862.3 mm standard length) of Pisodonophis cancrivorus (Richardson, 1848), family Ophichthidae, was first collected from the coast of Uljin-gun in Gyeongsangbuk-do, Korea in September 2008. This species is characterized by the following: fleshy protrusions of upper jaw in the front and rear of the posterior nostril, 3~5 irregular rows of granular teeth in bands on maxilla, mandible and vomer, and origin of dorsal fin above the middle of the pectoral fin. Based on the fleshy protrusions found on its upper jaw, a new Korean name "dol-gi-ba-da-baem" has been proposed for this species.
