Actinopteri (ray-finned fishes) > Lampriformes
(Velifers, tube-eyes and ribbonfishes) > Trachipteridae
Etymology: Trachipterus: Greek, trachys, -eia, -ys = rough + Greek, pteron = wing, fin (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 300 - 600 m (Ref. 35388). Deep-water; 72°N - 25°N, 62°W - 25°E
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)
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
Preferred temperature (Ref. 115969
): 2.7 - 10.4, mean 5.2 °C (based on 145 cells).
Phylogenetic diversity index (Ref. 82805
= 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).
Vulnerability (Ref. 59153
): Very high vulnerability (85 of 100) .
