Morphology | Morphometrics
Diagnosis: 161–199 total slime pores, trunk length 63.5–68.3% TL, tail length 10.9–14.0% TL, slime glands not visible under skin, body colour pale with clear lateral blue band, margin of cloaca and at least some slime pore rims blackish; differs from N. biniplicata by its trunk length (63.5–68.3 versus 55.6–61.2% TL), tail length (10.9–14.0 versus 14.4–19.3% TL), slime glands aspect (not visible under skin versus visible under the skin like a series of beads), body colour (pale with clear lateral blue band versus pink-grey), margin of cloaca colour (blackish versus whitish), and slime pores rim colour (at least some blackish versus same colour as surrounding tissues) (Ref. 115309).
Observed actively hunting a live red bandfish Cepola haastii (Ref. 115309).
