Item Lanternfishes (Family Myctophidae) Collected During SIBEX-Phase II Cruise in the Bransfield Strait, Antarctica(1986) Acuña, EnzoFour species of lanternfishes (myctophids) were captured in the southern area of the Bransfield Strait, Antarctica, during INACH SIBEX-Phase II cruise (summer 1985): Electrona antarctica, Gymnoscopelus (Gymnoscopelus) braueri, Gymnoscopelus (Gymnoscopelus) nicholsi and Protomyctophum (Protomyctophum) bolini. The diet, morphology and morphometry of the otoliths and the length - wet weight relationship of these fishes are analyzed. Copepods, euphausiids, Euphausia superba larvae and ostracods are the most frequent and/or numerous components of the stomach contents of these four Antarctic myctophids. An external morphological similarity between the otoliths of E. antarctica, G. braueri and P. bolini was observed. However, they can still be recognized as being from different species.
