Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 30-45; Épines anales 0; Rayons mous anaux: 13 - 18; Vertèbres: 47 - 52. Mouth large with two erect fangs on palatines. Dorsal fin very high, about three rays beginning with third or fourth much exerted; adipose moderate in size, over posterior part of anal insertion (Ref. 6885). Generally pale, iridescent, darker dorsally; lateral adipose keel dark; all fins dark brown or black; peritoneum black (Ref. 6885). Branchiostegal rays: 7-8 (Ref. 36025).

Biologie     Glossaire (ex. epibenthic)

Mainly inhabit tropical and subtropical waters; however, during the feeding period adults may migrate to the subarctic reaching as far north as Greenland, Iceland and the Bering Sea (Ref. 51887). Epipelagic- and mesopelagic, from near the surface to below 1,000 m, sometimes approaching inshore waters (Ref. 6011). Bathypelagic (Ref. 58302). Mainly nocturnal. Feed on fishes, cephalopods, tunicates, and crustaceans (Ref. 6011). Preyed upon by opah, sharks, albacore, yellowfin tuna, and fur seals (Ref. 6885). Oviparous, with planktonic larvae (Ref. 36025). Are synchronous hermaphrodites (Ref. 84733). Occasionally consumed but of little importance due to its soft flesh (Ref. 5217). The maximum weight given is for a 167 cm FL specimen (Ref. 42154).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Oviparous. Gonads of adolescents are hermaphroditic, but there is no proof that the species is a functional hermaphrodite (Ref. 6011). However, further studies show that this species is a synchronous hermaphrodite where gonads consist of clearly defined and well separated ovarian and testicular regions with no indication of sequential maturation of the sex products (Ref. 84733).
