Morphology | Morphometrics
Vertebrae: 160 - 166. Similar to Japonoconger sivicolus but with more head pores. Basic pattern of supratemporal pore seems to be a median pore flanked on each side by a pore midway to the lateral line and another pore immediately above the first lateral-line pore. Anomalies common, but no specimen less than four. Some specimens with one or two postorbital pores; Supratemporal pores show considerable variation, but no specimen has fewer than six.
