Kurzbeschreibung
Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt): 13; Rückenflossenweichstrahlen (insgesamt): 13-16; Afterflossenstacheln 3; Afterflossenweichstrahlen: 8 - 11; Wirbelzahl: 26. Head spines weak - nasal, preocular, postocular, tympanic and parietal spines present, supraocular, coronal and nuchal spines absent (Ref. 27437). Body slender and elongate; vent midway between origins of pelvic and anal fins (Ref. 27437). Posterior margin of caudal fin deeply indented (Ref. 6885). Greenish pink dorsally, fading to light ventrally (Ref. 27437). Branchiostegal rays: 7 (Ref. 36715).
Found in a wide range of habitats, sometimes in large schools well offshore and off bottom (Ref. 2850). Juveniles are pelagic (Ref. 36715). Adults feed on planktonic animals, mainly krill (Ref. 2850). Viviparous, with planktonic larvae (Ref. 36715). A very important prey species for predatory fishes and marine mammals (Ref. 2850). Not marketed due to its small size (Ref. 2850).
