Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 8 - 9; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 23 - 25; Wirbelzahl: 49. Color in alcohol: more or less yellow-brown, with intense pigmentation outlining scale pockets; pectoral and pelvic fins covered with small, scattered melanophores; black streak bordering anterior margin of eye (Ref. 6601).
Body shape (shape guide): elongated.
Oceanic, mesopelagic or bathypelagic species (Ref. 6601). The single known adult (holotype) was taken in haul between 657 to 0 m; most larvae have been taken in haul in the upper 500 m and in waters as shallow as 60 m. Probably feeds on other midwater fishes (Ref. 6691). Presumed to be synchronous hermaphrodites (Ref. 10755). Also Ref. 58302.
