Etymology: Nessorhamphus: Greek, nessa, netta = duck + Greek, rhamphos = bill, peak (Ref. 45335).

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; bathypelagic; depth range 0 - 1800 m (Ref. 58018). Deep-water

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Eastern Atlantic: France to Morocco; off the Cape, South Africa (Ref. 6592). Also known from temperate and subtropical latitudes of the western Atlantic, southwestern Indian, and southwest Pacific.

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 60.0 cm TL male/unsexed; (Ref. 123983)

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0. Dark brown in color (Ref. 6592). Snout long, depressed, and spatulate in form; lateral line distinct; pectoral fin long, subequal to snout; dorsal and anal fin rays abruptly become shorter near tip of tail and once again become longer, so it appears an independent caudal fin is present (Ref. 13608).

Biology     Glossary (e.g. epibenthic)

Mesopelagic (Ref. 5951). Feeds mainly on crustaceans.

Estimates based on models

Preferred temperature (Ref. 123201): 1 - 14.5, mean 7.8 °C (based on 1032 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.8750   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (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 vulnerability (44 of 100).
Nutrients (Ref. 124155):  Calcium = 26.4 [9.0, 58.4] mg/100g; Iron = 0.303 [0.134, 0.816] mg/100g; Protein = 18 [16, 21] %; Omega3 = 0.176 [0.058, 0.544] g/100g; Selenium = 22.3 [7.8, 62.8] μg/100g; VitaminA = 19.8 [2.3, 158.1] μg/100g; Zinc = 0.516 [0.280, 1.006] mg/100g (wet weight);
