Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 200 cm TL male/unsexed; (Ref. 9314); common length : 152 cm SL male/unsexed; (Ref. 6517); max. published weight: 150.0 kg (Ref. 47377)
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).
