Teleostei (teleosts) > Lampriformes (Velifers, tube-eyes and ribbonfishes) > Trachipteridae (Ribbonfishes)
Etymology: Trachipterus: Greek, trachys, -eia, -ys = rough + Greek, pteron = wing, fin (Ref. 45335).

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

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

Northeast Atlantic: Norway and Iceland to Madeira Islands; one report from Spain in the Mediterranean. Western Atlantic: New York to southern Florida in USA. Populations in western Atlantic are probably a separate species (Ref. 7251).

Length at first maturity / Size / Weight / Age

Maturity: Lm ?, range 200 - ? cm
Max length : 300 cm TL male/unsexed; (Ref. 35388)

Biology     Glossary (e.g. epibenthic)

Probably solitary although occasional aggregations have been reported, either for feeding or breeding purposes. Feeds on small fishes and squids (Ref. 6392). Sexually mature at a length of 200cm and an age of 14 years (Ref. 35388). Eggs, larvae, and young are pelagic (Ref. 6392).

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5166 [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) 		4.5   ±0.62 se; based on food items.
Generation time 15.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience
(Ref. 120179) 		Very Low, minimum population doubling time more than 14 years (tm=14; Fec = 500,000).
Fishing Vulnerability
(Ref. 59153) 		Very high vulnerability (85 of 100). 🛈
Nutrients
(Ref. 124155) 		Calcium = 10.1 [3.6, 22.3] mg/100g; Iron = 0.244 [0.106, 0.631] mg/100g; Protein = 19.3 [16.5, 22.9] %; Omega3 = 0.113 [0.047, 0.277] g/100g; Selenium = 25.1 [9.4, 74.0] μg/100g; VitaminA = 14.2 [1.8, 108.0] μg/100g; Zinc = 0.276 [0.152, 0.551] mg/100g (wet weight);
