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).
