বাস্তুসংস্থান
সামুদ্রিক; মহাসাগরে বিচরনক্ষম (Ref. 51243); গভীরতার পরিসীমা 0 - 200 m (Ref. 43). Subtropical; 42°N - 29°S, 98°W - 18°E (Ref. 43)
Eastern Atlantic and Mediterranean Sea: Positively known only from Madeira, Sicily (Italy), Strait of Gibraltar, and the adjacent Atlantic Ocean off southern Portugal. Can be expected to range widely in the eastern and perhaps central North Atlantic. Central and eastern Atlantic records from Japanese longliner's data need clarification. Highly migratory species.

Maturity: Lm ? range ? - ? cm
Max length : 184 cm FL পুরুষ/ লিঙ্গ অনিধর্ারিত ; (Ref. 43); 181.0 cm FL (female); সবের্াচ্চ প্রকাশিত ওজন : 21.5 kg (Ref. 43); সবের্াচ্চ প্রকাশিত ওজন : 21.5 kg
Further study is strongly needed to clarify the validity of this species. Probably oceanic. Length has been transferred from 'Body length' to FL (* 0.15).
