Ecology of Sternoptyx diaphana
Main Ref. Hopkins, T.L. and R.C. Baird, 1985
Remarks Oceanic and non-vertical migrant (Ref. 4739). Commonly found in 500-800 m both day and night (Ref. 4054). Possibly a cyclic feeder of copepods, ostracods, euphausiids, amphipods, fishes and other taxa (Ref. 4739). Feed on fewer but larger prey items from regions of cooler overlying water massess and diet was less diverse than that of fish from warmer waters (Ref. 54153). Larger specimens feed on larger food items. Feeding strategy appears to involve capture of the nearest "available" prey within its immediate vicinity (Ref. 54153). Adult photophore complement acquired at 11-13 mm SL (Ref. 4739). Lipid content 1.4 % in fresh body weight and wax ester is 4.2 % in total lipids (Ref. 9193).
