Size / Weight / سن
Maturity: Lm ? range ? - ? cm
Max length : 39.0 cm TL جنس نر / بدون خواص جنسي; (Ref. 4412)
خارهاي باله پشتي (کل) : 9 - 13; شعاع نرم باله پشتي (کل) : 24 - 28; خارهاي باله مخرجي: 1 - 2; شعاع نرم باله مخرجي: 24 - 29; مهره ها: 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).
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).
