Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

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).
Body shape (shape guide): eel-like.

Observed actively hunting a live red bandfish Cepola haastii (Ref. 115309).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00115 (0.00044 - 0.00298), b=3.03 (2.80 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.6 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (46 of 100). 🛈
