Description synthétique Clés d'identification | Morphologie | Morphométrie

Rayons mous dorsaux (Total) : 20; Épines anales: 0; Rayons mous anaux: 18; Vertèbres: 22. Absence of dorsal and anal spines and of pelvic fins contribute to streamlining of the body, as does the flat and relatively consolidated opercular spines (Ref. 11017, p. 74).

Oceanic and epipelagic; found near surface or in deep water (Ref. 10821). Apparently solitary (Ref. 9314). Feed mainly on jellyfishes, ctenophores, and other gelatinous planktonic animals (Ref. 2850, 6885). Spawning starts at the end of spring and during the summer (Ref. 9314). Juveniles unlike adults in that the median fins are longer and further forward, the mouth toothed and the body and fins black-spotted (Ref. 6517). Rarely found in markets (Ref. 9314).

Estimates based on models

Preferred temperature (Ref. 115969): 10.1 - 28.2, mean 24.6 (based on 1668 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.8 ±0.46 se; based on food items.

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Catégorie de prix (Ref. 80766): Unknown.
