Western Atlantic: Newfoundland, Canada and northern Gulf of Mexico to Brazil (Ref. 7251). Eastern Atlantic: north-west Africa and the Canary Islands (Ref. 4777); also São Tomé Island (Ref. 34088). Not recorded from the Mediterranean and most of the eastern Atlantic (Ref. 9834). Indian and Pacific: widely distributed.

Maturity: Lm ? range ? - ? cm
Max length : 39.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 4412)
背棘 (總數) : 9 - 13; 背的軟條 (總數) : 24 - 28; 臀棘: 1 - 2; 臀鰭軟條: 24 - 29; 脊椎骨: 41. Juveniles whitish or silvery with dark blue mottlings; pelvic fins black (Ref. 4412). Dark blue above, side silvery with patches of dark blue. Pelvic fin with inner rays joined to abdomen by membrane for its entire length (Ref. 26938).
稚魚微白色的或銀色的有深藍色雜斑; 腹鰭黑色.(參考文獻 4412) 背面深藍色的, 側邊銀色的有深藍色的區塊。 腹鰭有內部的鰭條對於它的整個長度連到了薄膜的腹部.(參考文獻 26938)
Found offshore in warm waters. Juveniles pelagic in coastal and offshore waters down to at least 30 m, but adults possibly demersal in deep water (Ref. 9563). Occur in association with floating Portuguese man-of-war, Physalia, feeding on its tentacles and gonads and may drift with it into shore waters with proper wind conditions (Ref. 4777). Probably also feed on other soft-bodied jellyfish as well as on zooplankton (Ref.4777).
在溫暖的水域中發現於外海了。 稚魚大洋性的，在沿岸與離岸水域中向下至至少 30 公尺, 但是成魚可能底棲在深水中.(參考文獻 9563) 與漂浮的葡萄牙軍艦水母 , Physalia 一起生活, 吃它的觸鬚與生殖腺而且可能與他一起漂流進入沿岸水域在風的條件適合情況下.(參考文獻 4777) 可能也吃其他的身體柔軟的水母以及浮游動物。 (參考文獻 4777)
