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.

Bayesian length-weight: a=0.00066 (0.00030 - 0.00147), b=3.16 (2.96 - 3.36), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.9 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
