Teleostei (teleosts) > Anguilliformes (Eels and morays) > Nettastomatidae (Duckbill eels)
Etymology: Nettastoma: Greek, netta = duck + Greek, stoma = mouth (Ref. 45335); melanura: From the Greek melan meaning black, dark, and oura meaning tail, referring presumably to the dark edges of the posterior part of the dorsal and anal fins..

Short description Morphology | Morphometrics

Vertebrae: 190 - 210. Usually five supratemporal pores, SO5 absent. Lateral line pores 43-49. Median vomerine teeth somewhat enlarged. Posterior nostril near anterodorsal margin of eye.

Estimates based on models

Preferred temperature (Ref. 123201): 5.4 - 14.4, mean 10.2 °C (based on 488 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00095 (0.00067 - 0.00137), b=2.95 (2.85 - 3.05), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.50 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (52 of 100).

Nutrients (Ref. 124155): Calcium = 12.3 [2.9, 50.7] mg/100g; Iron = 0.319 [0.093, 1.082] mg/100g; Protein = 18.2 [15.8, 20.8] %; Omega3 = 0.172 [0.056, 0.548] g/100g; Selenium = 15.7 [4.0, 65.6] μg/100g; VitaminA = 13.5 [1.5, 108.4] μg/100g; Zinc = 0.42 [0.19, 1.05] mg/100g (wet weight);
